While on the subject of pub jokes...
A bloke walks into a Darwin pub dragging a live, eight-foot saltwater crocodile with him.
He says to the barman, “If I put my dick this crocodile’s mouth for 15 seconds without it being bitten off, will you give me free drinks for the night?”
The barman tells him he’s mad but agrees so, before the gathered crowd, the bloke slowly prises open the crocodile’s jaws and puts his dick between its teeth. The crocodile swiftly closes its jaws but stops just short of his dick. Then, after 15 seconds, the bloke hits it over the head with a beer bottle. The now-disoriented crocodile opens its jaws wide, allowing the guy to safely take out his dick.
The barman is shocked but, as agreed, starts serving the promised free drinks.
The bloke then announces to the bar, “If anyone else can do that, I’ll buy them free drinks for the night too.”
After a stunned silence a gorgeous young blonde steps forward and says, "Ok, I’ll do it - just as long as you don’t hit me on the head as hard as you hit that croc!”
