Two aliens landed in the West Texas desert near an abandoned gas station.
They approached a gas pump. One alien addressed it: "Greetings, Earthling. We come in peace. Take us to your leader."
The gas pump didn't respond.
The alien repeated the greeting. Still, there was no response.
Annoyed by what he perceived as the pump's haughty attitude, the alien drew his ray gun and said impatiently, "Greetings, Earthling. We come in peace. How dare you ignore us! Take us to your leader, or I'll fire!"
The other alien shouted, "No, you don't want to make him mad!" But before he finished, the first alien fired.
A huge explosion blew them 200 meters into the desert, where they landed in a heap.
When they finally regained consciousness, the one who fired said, "What a ferocious creature! It damn near killed us! How did you know it was so dangerous?"
The other alien answered, "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!"
