I see your Leo Sayer, and invoke the mighty power of Juan Luis Pedro Phillipo de Huevos Epstein, otherwise known as Welcome Back Kotter's Juan Epstein (Robert Hegyes):

Cosmo, you're not going to win this, so don't even try. You'd best quit this before the Big Dig comes to you, if you know what I'm saying.
Signed,
Epstein's Mother.
