fishing joke

ok so its not new but its been a long time since I last heard it.

Two blokes out for a long fishing session in a boat in the middle of a lake
and one catches a large pike of which the belly is wriggling, the angler
cuts open the pike and out jumps a genie
"thank you for rescuing me for that I will grant you one wish" says the
genie
quick as a flash the angler says "as we have just drunk the last can you can
turn the water of this lake into beer"
" It is done" says the genie who disappears in a puff of smoke
"You Pratt" says the other angler "now we have to **** in the boat"
