The Big Bang Theory, "The Fetal Kick Catalyst"
Sheldon and Amy's experiment in hosting a peaceful brunch hit a few snags when Stuart learned he was there as a "test-run" guest. Realizing he hurt a loyal friend, Sheldon apologized to Stuart and proposed a toast to the comic book store owner.
To see the two pals get tipsy on bubbly, watch "The Fetal Kick Catalyst" on CBS All Access.
