[Damocles]

Three Irish guys go into a pub, have a few pints and are ready to leave and pay their tab. The bar back brings them a bill for exactly £30.00. Each guy gives him a tenner, and they leave.

When the bar back hands the £30.00 to the bartender, he is told a mistake was made. The bill was only £25.00, not £30.00. The bartender gives the bar back five £1.00 notes and tells him to take it back to the 3 Irish guys.

On their way out of the pub, the bar back has a thought... these guys did not give him a tip. (Editor's note: yes, I know they do not generally tip in Ireland, please just play along…) He figures that since there is no way to split £5.00 evenly three ways anyhow, he will keep two pounds for himself and give them back three pounds.

OK! So far so good!

He taps one of the guys on the shoulder and explains about a mix up in the bill, and hands the guy the three pounds, then departs with his two-pound tip in his pocket.

Now the fun begins!

Remember £30-£25=£5 Right? £5-£3=£2 Right?
So what's the problem?
All is well, right?
Not quite… Answer this:
Each of the three guys originally gave £10.00 each.
They each got back £1.00 in change.
That means they paid £9.00 each, which times three is £27.00.
The delivery boy kept £2.00 for a tip.
£27.00 plus £2.00 equals £29.00.
Where the heck is the other pound??????????
