5 Just One Bite

When SpongeBob learns that Squidward has never tasted a Krabby Patty, it becomes his obsession to get his co-worker to take even just a bite, believing that it is the reason why he is "always so miserable." After several attempts of making him taste the sandwich, Squidward finally gives up and tries the patty. He pretends to hate it at first, but actually likes it. Squidward gets obsessed and desperate for more (despite SpongeBob's protests that Squidward should not eat too many Krabby Patties at one time), and as a result blows up after eating thousands of Krabby Patty sandwiches in a vault full of them.
