An actuary, an accountant, an old lady, and a beautiful blonde find themselves together on a train. The train passes through a tunnel and in the darkness a loud slap is heard. When out of the tunnel and in the light, they see that the accountant has a red five fingermark on his cheek.
The blonde is thinking: the accountant must have tried to grope me in the dark and mistakenly groped the old lady, so she slapped him. The old lady is thinking: that guy must have groped the blonde in the dark and she slapped him. The accountant is thinking: the actuary must have groped the blonde in the dark and she mistakenly slapped me instead of him. The actuary is thinking: I can't wait for the next tunnel so I can slap that damn accountant again!!!
