Ive got a better one,
2 guys are hunting in the bush one day while they are walking one has a heart attack. The other guy pulls out his mobile and calls for help. He says "I need an ambulance my friend has just colapsed".
The Operator says "Ok, first make sure hes dead".
A moment later the Operator hears... BANG!
The guy comes back onto the mobile and says now what?
xD
