Valentine's Day (SpongeBob SquarePants)

Synopsis
On Valentine's Day, SpongeBob is giving out Valentine's Day hearts. He even gives one to Plankton, which is delivered with the help of tweezers. SpongeBob and Sandy have arranged to give Patrick a hot air balloon made out of chocolate. SpongeBob tells Patrick that he has the best present ever for him, and the two go to the Valentine's Day carnival, with Patrick extremely excited for his surprise present.

Meanwhile, Sandy, who is in route to the carnival in the chocolate balloon, is attacked by a flock of scallops, which causes the balloon to veer off course as she fights them off. When SpongeBob and Patrick reach the top of the Ferris wheel, where the surprise is to be revealed. However, Sandy contacts SpongeBob via walkie-talkie, informing him of her troubles and telling him that he will have to go with "Plan B." SpongeBob tells Patrick, who is so excited that he is literally shaking the entire Ferris wheel, that his present is a "friendly handshake," greatly disappointing him and making him very angry.

When Patrick sees many other people, including complete strangers (one man only asks for the time), thanking SpongeBob for his gifts to them, he is pushed off the deep end and goes on a rampage. He begins destroying the carnival and corners everyone there, including SpongeBob, seemingly with the intention of killing them all. Before he gets the chance, however, Sandy arrives, having tamed the scallops, who are now helping to keep her balloon afloat. Upon seeing this, Patrick takes a bite of his present, causing it to pop and covering the carnival in chocolate. Smiling at SpongeBob and completely forgetting his anger, Patrick joyfully says, "Aww, SpongeBob, you didn't have to get me anything" as the episode ends.
