How I Met Your Mother: 10 Unforgettable Running Jokes

8. The Pineapple Incident

First appeared in: 'The Pineapple Incident' In season one, the How I Met Your Mother gang did a 'Hangover' four years before that film had even been released, presenting Ted with the assorted remains of a drunken one-night stand that he couldn't remember. Among them were a burn on his coat, a sprained ankle, and a single pineapple on his bedside table. Of all the questions that lingered on fans' minds in the lead-up to the finale, The Pineapple Incident remains an enigma to this day. During the episode, Ted was left piecing together scattered memories of his night as a result of drinking five shots of €œRed Dragon€, a blood-red concoction created by McLaren's bartender Carl. While he was able to determine that the girl in his bed wasn't Robin (and that, to his relief, his record of being €œvomit-free since '93€ remained intact), the secret of the pineapple was left unsolved. Creator Craig Thomas has allegedly hinted at a potential video that could clear up outstanding questions surrounding certain elements of the show. Could this mean that the Pineapple Incident will finally reach its long-awaited conclusion? The answer could well be hidden away in an upcoming DVD release or the series' hotly-anticipated alternate ending. For now, though, the mystery lives on.
