I've been watching this show since middle school and ad cheesy as it sounds, it's helped me through some tough times. There were times where it was the only thing that made me laugh.
On a more light hearted note, I've never gotten through an episode without laughing! I love seeing their friendship and seeing how people react to them. Their laughter is so contagious and even if what they're saying isn't super funny, their dumb facial expressions will get me laughing!
A++ show and I'll be sad the day it ends.
