Three mexicans are caught trying to cross the Mexico-USA border and arrested by an american policeman. This particular policeman, having his own strange taste, offers them a deal:
"If your penises together reach one meter, i'll let you guys go; if not, you're busted."
So the first of the mexicans pulls his pants down: 90 centimeters.
The second pulls his down: 9 centimeters.
The third one pulls his down: barely one centimeter.
The three mexicans are cheering and happy, and the policeman, satisfied with what he saw and true to his word, lets them go. After that, the mexicans are congratulating each other.
"Shut up," the first one says. "If it weren't for my 90 centimeters, we would be in jail."
"Well, i didn't do so bad myself," the second one replies. "9 centimeters is okay, i think."
"Oh, shut up, you tarts," the third one says. "If i hadn't gotten excited, neither of us would be here."
