No, it wouldn't have worked with Yakkety Sax. The difference between Frolic and Yakkety Sax is Frolic is utter and complete failure at a situation one has become too invested in proven trivial (hence "Curb Your Enthusiasm") and Yakkety Sax is Benny Hill being chased by the angry pub owner for kissing his wife.
