Dooo iiiit! It's an hilarious show and I'm frequently embarrassed by the fact that I basically can explain the many geek jokes to my friends, haha.
Although I must say, huge missed geek apportunity for the show when the four guys wanted to dress up as the Flash and looked the same. There's plenty of variations to choose from, everyone can be a Flash!
Also you may want to youtube "The Big Bang Theory - Penny's Christmas gift to Sheldon" for a big laugh.
