When Raj is selected as an up and coming scientist by People magazine, he gets a Superdome sized head. His friends are jealous, but agree to take him to dinner. Sheldon is made to smile which is one of the funniest things I've ever seen (with or without teeth). Everntually, he gets a date with Penny with some sad results (of course, he has to drink to be able to talk to her). Very funny episode.
