Not sure if I am thinking of one episode or two separate ones.
-Kramer is in Jerry's apartment talking to Elaine and she says "Well maybe the something? is in your apartment." And Kramer says "You just blew my mind."
-Kramer is talking to Jerry and says something to the effect of his world crumbling around him and something about his head spinning like a top.
Sorry last description is very vague. I just can't seem to figure out which episode(s) these are from. I've seen every show like a million times but I can't place these.
Any help would be good.
