i do feel the same way about dane, after his troubles with his brother and his crazy rise to fame he didn't seem to handle it well on the mental side of things, but i kind of enjoy his over the top forced joke telling style, it's silly and it isn't the way you would tell a joke to your friends but he pulls it of imo,
and i don't think i'v seen that episode of BBT, i liked the show a little more before the Jewish guy got a girlfriend, he was the character on the show that really made me laugh, but now kinda like chandler and Monica becoming a couple it took something away from his comedy
