080b - The Gift of Gum
On "Best Friend's Day," Patrick gives SpongeBob an enormous wad of used gum he has amassed over his entire lifetime (fondly referred to as "Gummy"), and SpongeBob finds it a better gift than his own (a robotic butler). However, when he takes it inside, he realizes how disgusting it is, and it even starts to scare him, with a pair of underpants crawling out of the gum and saying in a demonic voice, "You're not Patrick!" First, SpongeBob tries to throw it away, but Patrick catches him in doing so, and he says that he was dressing it up with the garbage can. Later, SpongeBob tries to bury Gummy, but Patrick catches him again, and he says that he dug the hole to be able to look at Gummy from below. Patrick insists that it must be displayed properly, and places it above SpongeBob's doorway. SpongeBob next tries to dispose of it in the night, and in the process frees several people who were literally trapped inside it. He tries to pull Gummy off of his house, and fails, destroying the ball and getting stuck to it in the process.
The next day, Sandy visits SpongeBob's house to see it covered in the sticky remains of Gummy, with SpongeBob hanging above his doorway. She tries to free him by lassoing a piece of Gummy onto a passing truck, which is almost able to pull it away, but is ultimately pulled in by it, hitting SpongeBob's house and causing the gum to explode, completely covering the houses of SpongeBob, Squidward and Patrick, and trapping Squidward and Sandy as well. Patrick then appears, and SpongeBob tells him he can have Gummy back. Patrick then wolfs down all of the gum making Patrick obese, freeing SpongeBob, his friends and their houses. However, he then hiccups a massive bubble, which explodes and covers the whole town in gum.
