3 Gaping Plotholes in How I Met Your Mother
Since I have watched the series from start to whatever is currently airing about a - to quote Robin - “floppity-jillion” times (in reality, probably somewhere close to 15 times), I have started to pick up on little continuity errors throughout the series. Here are three examples that I think are significant enough to actually bother me, as they affect character personalities.
1. The not-so first time Marshall saw Lily pee
In the episode entitled “Zip, Zip, Zip” (Season 1, Episode 14), there is quite the dramatic, relationship-defining moment between Marshall and Lily as they get trapped in the bathroom and realize they have no more ‘firsts’. Since Ted and Victoria are taking forever to go to the bedroom and Lily has to pee, Marshall and Lily must face something they have been dreading for a long time – the first time Marshall sees his fiancée go to the washroom. The situation is finally dealt with when they realize that even though this wasn’t something they wanted to do, it was a ‘first’ and they are happy.
What this episode misses entirely is that in the episode entitled “The Slutty Pumpkin”, Marshall and Lily dress up like a pirate and a parrot to win a costume contest at the bar. Right after they come out to show Ted their costumes, Lily announces she has to pee. When Marshall starts to follow her, Ted asks where he’s going. Marshall looks a bit uncomfortable and says, “It’s an elaborate costume”. This would obviously imply that the parrot costume is so big and fluffy that it needs a second pair of hands to hold it up while peeing.
Therefore, Marshall saw Lily pee before the huge ordeal they make out of it in the later episode.
2. Lily’s not-so huge estrangement from her father
In the episode entitled “Slapsgiving 2: Revenge of the Slap” (Season 5, Episode 9), the main drama and character development is the father that Lily has apparently not spoken to in three years comes back on Thanksgiving to try and reconnect with his daughter. There is a very emotional moment when we find out that Marshall went to talk to Mickey only to find out the poor man was heartbroken – Lily never returned his calls, and despite the fact that he wrote a speech for the wedding, the invitation never came because Lily was still so mad at him.
However, in the episode entitled “Something borrowed” (Season 2, Episode 21), we find out that during the planning of the wedding nothing has been going right. There is a brief montage of Lily walking into the room announcing various changes (“It’s not going to be an outdoor wedding anymore, because Marshall’s father thinks if we have an outdoor wedding in New York he’ll get mugged”). One of the changes is “You know how we were going to have an acoustic guitar? Well now we’re having a harp player. My dad owes someone a favor and his daughter plays the harp”. This implies that Lily had contact with her father during the planning stages of the wedding.
Therefore, one of Lily’s defining moments as a character was a totally huge hole in the plot.
3. Marshall’s not so bad at fighting anymore
In the episode entitled “Sweet taste of Liberty” (Season 1, Episode 3), we see Lily have a girl’s night out with Robin while Marshall studies for law school. Lily quickly finds out that all the available men in the bar are hitting on Robin, so she calls Marshall, who assures her that the only reason all the guys aren’t up in her business is because of her engagement ring. After removing the ring, Lily believes she has finally gotten a guy’s attention… only to discover that he is gay, and was walking over to tell her that she sat on a grape. After almost driving to Philadelphia, Marshall gets so worried about his advice to Lily about taking her ring off that he arrives at the bar and finds the aforementioned gay man wiping the grape juice off Lily’s butt. He threatens to fight the man, but as soon as Lily shouts out, “He’s gay!” Marshall hugs the man and whispers, “Oh thank God – I’ve never been in a fight before!”
Apparently all this is forgotten in the episode entitled “The Fight” (Season 4, Episode 10), where the bartender Doug gets the men in the group involved in a fight after kicking some other guys out of their favorite booth. Marshall decides not to fight, though he claims he fought often with his brothers (which is mocked severely by other members of the group). It is finally revealed at the end of the episode that Marshall’s fights with his brothers were like Fight Club – with all the blood and bone-breaking intact.
So convenient, how they forget these things.
