The closest examples I can think of of post-Season One Bert being "mean" to Ernie include an old-school bit from the 70s, where Ernie and Bert are at the movies, but everything Ernie does keeps making too much noise, from unwrapping a candy bar, to eating peanuts, to sipping soda, to which Bert finally blows up at Ernie to be quiet... but then, Bert got his when an usher came down to remove the noise-maker, who he saw was Bert, because he was yelling when he came in.
That, and from the "Adding" bit from the 90s, where Bert blows his top so much that he's screaming like a girl "ALL I WANTED TO DO WAS SIT AND READ BY MYSELF IN PEACE AND QUIET, BUT NOW THERE'S MONSTERS AND COWS AND ELEPHANTS AND MARTIANS HERE! YOU KNOW WHAT I THINK, I THINK YOU SHOULD TRY SUBTRACTION! TRYSUBTRACTIONTRYSUBTRACTION! ! !"
I think that's about as "mean" as Bert ever got after Season One or so. Well, that and an aired-once bit from the 80s (I think) where Bert finally had it with Ernie's midnight capers, and ran into the other room, where he could be heard screaming, and breaking dishes or something.
