Hello, I'm new to this forum, so I stopped by to say "Hi" (hello, actually) and ask you all a question about today's episode. When Raj and Leonard made a funny comment on Howard's problem, they touched the tips of their index fingers together to celebrate. I'm totally clueless as to what the idea behind that celebration is. Is it some kind of reference to a character in a comic book or a movie? All I could find on the internet were references to Star Trek: Voyager's Q and his female counterpart mating through that method, but I don't think that's the case.
Any help is appreciated.
Thanks in ad
