[Lazy]

A duck walks into a bar and asks, "Got any g****s?"

The bartender, confused, tells the duck no. The duck thanks him and leaves.

The next day, the duck returns and asks, "Got any g****s?"

Again, the bartender tells him, "No -- the bar does not serve g****s, has never served g****s and, furthermore, will never serve g****s." The duck thanks him and leaves.

The next day, the duck returns, but before he can say anything, the bartender yells, "Listen, duck! This is a bar! We do not serve g****s! If you ask for g****s again, I will nail your stupid duck beak to the bar!"

The duck is silent for a moment, and then asks, "Got any nails?"

Confused, the bartender says no.

"Good!" says the duck. "Got any g****s?"
