You sing:
(Dough) – I use to buy my root beer, Re (Ray) – The guy who pours my root beer, Mi (Me) – The guy who drinks my root beer, Fa – A long way to the bathroom, So – Let’s have another root beer, (La) Lots and lots of lovely root beer, Ti (Tea) – No thanks, I’m having root beer, And that’s why I have no dough, dough, dough, dough.
Everyone laughs, and the tension is diffused.
