Two aliens landed near an abandoned petrol station.
They approached one of the petrol pumps, and one of the aliens addressed it,
"Greetings, Earthling. Take us to your leader."
The pump didn't respond. The alien repeated the greeting. No response. The alien, annoyed by what he perceived to be the pump's naughty attitude, said impatiently,
"Greetings, Earthling. Take us to your leader, or I'll fire!"
The other alien shouted to his comrade
"No, don't make him mad!"
Before he finished his warning, the first alien fired. There was a huge explosion that blew them 200 meters into the woods, where they landed in a heap. When they finally regained consciousness, the one who fired turned to the other one and said,
"What a ferocious creature. How did you know it was so dangerous?"
"If there's one thing I've learned during my travels through the galaxy...any guy who can wrap his dick around himself twice and then stick it in his own ear, is someone you shouldn't mess with!"
