Pun intended

"The quality of a bar in São Paulo is measured in large part by its chopp (SHO-pee), the Brazilian-style draft beer.(...) The undisputed chopp masters can be found at Bar Léo, a German-themed joint in the city's gritty center. To test the barman's skills, ask for a leitinho (lay-CHEEN-yo), all head and no beer".

Retirado daqui.

Leitinho, all head and no beer... Piada mais pronta, impossível. A zoação só seria maior se o figura chegasse ao Léo e pedisse chopp sem colarinho...
