MST3K made me a funnier person.
Listening to the rapid-fire cultural references and stunning delivery of all the performers, you wish to emulate them. You'll start putting on your wacky radio announcer voice which if you can do well, just sounds funny no matter what you say, and then if you can spout an obscure, Dennis Miller-esque reference at the same time, it's basically instant side-splitting guffaws.
Also funny is when you see a shot of someone's face on TV or in a movie, to be able to blurt out a name of someone they sort-of look like, and other people can see it even if it's a little strange, is something that ultimately gives you power over people.
