Reminds me of this one:
A trainee parachutist asked the instructor "What if the 'chute fails"?
Instructor: "The chances of that are 1 in a million, but if it does fail, use the reserve".
Trainee: "What if that fails"?
Instructor: "Well, that's a one in a trillion chance. In which case, pray to Allah".
Come the day of his first jump, the trainee's 'chute does indeed fail. Twenty seconds later, with a 2 pound load of moist manure moisturising his nether regions, he remembers the reserve 'chute.
Hurtling towards the ground at 120 mph and certain death he remembers the instructor's advice.
"Oh Allah! Oh Allah! Save me! Save me"!
Instantly, from out of a cloud, a huge upheld palm catches the trainee, slows his decent, and places him gently upon the ground.
The trainee is overwhelmed.
"Jesus Christ"!! he exclaims.
And a great big foot appears from out of the same cloud and pulverises him into the ground.
Note: feel free to substitute any other deities if you re-tell this and are afraid of the PC brigade / mind police / religious fanatics. Pink elephants have VERY big feet.
