This is basically the same formula as a Friar Tuck, and I guess there must be a whole class of creamy cocktails like this. One could have fun naming them:
cream + creme de cacao + Liquor 43 = Golden Squirrel
cream + creme de cacao + creme de bananes = Squirrel Monkey
cream + creme de cacao + nux alpina - Squirrel Nutkin
Any others that come to mind?
