While most fans of ‘How I Met Your Mother’ know the show isn’t amazing because of its consistency, it’s tough getting a grip on the story when things aren’t adding up. Here are some of the biggest plot holes from the show.

In season 5, episode 14, Lily and Marshall both tell everyone that they share one single toothbrush. Of course, the couple also lives with Ted, who claims that this is also the toothbrush he uses. Then, Robin chimes in, explaining she used it too when she was dating Ted.
Everyone’s grossed out, but they ultimately move on. However, all the way back in season 1, episode 14, Lily and Marshall are clearly seen brushing their teeth at the same time.
