With that many funny moments, it's hard to whittle them down to the absolute best, but this video gathers some of the ones that made us laugh the hardest, like Sheldon (Jim Parsons) giving Amy (Mayim Bialik) a spanking that she enjoys a little too much, Raj (Kunal Nayyar) checking to see if Howard's (Simon Helberg) boobs got bigger, and of course Fun with Flags, Sheldon's long-running web series and the show's best recurring joke.
Of course, if this was to be comprehensive, it would be hours long. So what are your favorite moments that didn't make the cut this time?
