Fun with mathematics

I saw a poster recently for a country music channel, which made the following claim
"Tattoos: Eminem - 8 Dixie Chicks 27".
Well, that's all very well, I thought, but there are three Dixie Chicks, so that's hardly a convincing argument that they have more tattoos than Eminem. But, then I applied the probabilistic method. There is an average of 9 tattoos per Dixie Chick. Therefore, there must exist a Dixie Chick with 9 or more tattoos, more than Eminem. Isn't mathematics wonderful?
