I'm a fan. I suppose I can't claim to have never groaned at a forced pun, but I really do appreciate that sort of thing most of the time.
Tonight, I was talking to my roommates about massages and one of them told us about a lady that once gave him a great one.
"She's a really good. . . massager. . . massoose. . ." he said.
"Misogynist," I said. No one laughed. They either didn't get it or didn't think it was funny. Either way, it made me sad.
