When you wake up the next morning, you have to take the good with the bad. For instance, hooking up with a woman? Good! Burning your coat? Bad. Getting a random phone number? Good! Spraining your ankle? Bad. The pineapple... remains a mystery.

Some of How I Met Your Mother's greatest episodes unfold as the gang works together to solve a groovy mystery. So, if the series's habit of continuity and recurring gags holds out, we'll be over the moon to learn the epic secrets behind the pineapple on Ted's nightstand sometime in the last season!
