Funny?

Two aliens landed in the New Mexico desert near a gas station that had been
closed for the night.
They approached one of the gas pumps and the younger of the two aliens addressed
it. "Greetings, Earthling. We come in peace. Take us to your leader."
The gas pump (of course) didn't respond.
The younger alien started to get mad at the lack of response and the older one
said, "I wouldn't do that if I were you."
The younger alien ignored the warning and repeated the greeting.
Again, there was no response.
Annoyed by what he perceived to be the pump's haughty attitude, he drew his ray
gun and said impatiently, "Greetings Earthling. We come in peace. Do not ignore
us in this way! Take us to your leader, or I will fire."
The older alien again warned his comrade, "You don't want to do that; You really
don't want to make him mad!"
"Rubbish,!" replied the younger alien. He aimed his weapon at the pump and
fired.
There was a huge explosion.
A massive fireball roared outwards and towards them and blew the younger alien
off his feet and deposited him in a burnt and crumpled mess 200 yards away in a
cactus patch.
Thirty Earth minutes later, when he finally regained consciousness, refocused
his three eyes and straightened his bent antenna, he looked dazedly up at the
wiser one, who was standing over him, slowly shaking his big green head.
"What a ferocious creature," said the young fried one. "It damn near killed us!
How did you know it was so dangerous?"
The older alien leaned over, and said "If there's one thing I've learned during
my travels through the galaxy," "When a guy has a pecker he can wrap around
himself and stick it in his ear; you don't mess with him."
