I conducted my own survey, and here's what I found (**):
- Wolowitz thought it was hilarious.
- Sheldon, as intelligent as he is, didn't get it.
- Leonard couldn't decide if it was funny or not, but said he would have at least had the good sense to not post it publicly.
- Raj had absolutely nothing to say about it (but that may have been because Penny was in the room).
- Penny thought it had something to do with Star Trek.
I'm still waiting to hear from Amy and Bernadette.
(**) I didn't really ask them. If you wanted to know what they really thought about it, you would probably have to ask Chuck.
