I've gotta say, since Junior High School, I've been pretty good at predicting random trends in comedy before they saturate & eventually over-saturate pop culture. Here is a chronological list dating back to '86 of some of my success.
Midgets, mimes, donkey polo, monkeys, ham sandwiches, pimps, ninjas, Christopher Walken, unicorns, lucha libre, muscle car dirtbags, monocles, mannequins, 50's style robots, hobos, people in lobster suits, colonial pilgrims, widespread panic, radial tires, the internet and brown sugar (just to mention a few).
This years random pop culture prediction has been: Alpacas, alpacas, alpacas!
(Yes, this is a real commercial)
