side effect of volcanic eruption

[Bitter End]

Mike and Jim were a couple of drinking buddies who worked as aircraft mechanics at Glasgow Airport ..
One day the airport was on stop because of the Iceland Volcano eruption and they were stuck in the hangar with nothing to do.
Mike said, "Jeez, I wish we had something to drink!".
Jim says, "Me as weel. Y'know, I've heard ye can drink jet fuel and get a buzz. Ye want tae try it?
So they pour themselves a couple of glasses of high-octane hootch and get completely blootered.
The next morning Mike wakes up and is surprised at how good he feels.
In fact he feels GREAT! NO hangover! NO bad side effects. Nothing! Then the phone rings...It's Jim.
Jim says, "Hey, how do you feel this mornin'?"
Mike says, "Brilliant! Whit aboot yerself?"
Jim says, "I feel great, too. Do ye have a sair heid?"
Mike says, "Naw, that jet fuel is great stuff - nae hangover, nothin'.
We need tae drink this stuff insteed o' the Smirnoff."
"Aye! But there's just one thing..."
"What's that?".
"Have you farted yet?"
"Naw..."
"Well, DINNAE,

'cause I'm in Dusseldorf!"
