he really like this joke, its extemely lame, but earsn a laugh forits lameness.
a duck walks into a bar and goes to the barman, "do you have any bread?" the barman replies "no we don't have any bread but we do have beer" the duck walks out.
a few minutes later, the duck walks back in again and goes to the barman "do you have any bread?" the barman looks at the duck and says "no."
a few minutes again the duck walks back in again, walks up to the barman and says, "do you have any bread?" the barman, being a busy person is getting impatient, and goes "look mate, i don't have any bread, and if you ask me again, i'm going to nail you to that door over there!"
the duck thinks about this for a few seconds, and then says "do you have any nails?" barman goes "no". the duck then says "do you have a hammer?" "no"
"then do you have any bread?"
very lame, yes i know
