Re: Always blow on the pie!
Its actually a common practice to ask weird questions like that, to catch the people off-guard. For example;
"You carrying anything I should know about? Any weapons or something that'll stick me? Any guns, knives, needles or tanks?"
An innocent person would go "Tanks? In my pockets?!". But the person the cop was asking (it was on an episode of COPS) simply went "No, no, no...." which raised the officer's suspicion and in the end the guy turned up to be a drug runner with guns and dope on his person.
