Kramer is what's different now

Seinfeld used to be about the guys sitting around picking at life and talking about things we think about but don't realize. Like whether nose picking is actually gross, or how you have to break up with someone in person after seven dates. "If it was six I could have let you go," Jerry says to Elaine. Sure the episodes are still funny, and for a while I kept thinking "Wow, they AREN'T running out of ideas." But in the end you realize that they actually are, that's why they have to come up with weird stuff like Kramer adopting a highway, getting obsessed with a meat slicer, storing his blood in Jerry's apartment, shaving with butter, etc. Now that I think about it, Kramer is mostly what's different. Each episode, they try to figure out ways for him to get weirder and weirder, and his facial expressions are so strange now. He used to be about just kind of having weird ideas and not really understanding things the way "the humans" do.

That's why I think Kramer should be abducted by aliens. Regina

If that happens in the last episode, I'll have to kill myself
