The Big Bang Theory's episode number 22 of season 3 actually has a subtitle of The Staircase Implementation. However, since this is the episode that tells about how the two key casts [Sheldon and Leonard] of the show meet for the first time, I call this episode "The Beginning".
This episode was aired on the 17th of May and just like all the other episodes, this one never failed to make me and Bebe laugh out loud.
