There once was an english man, a french man, and a newfie, they were all on to of the CN tower one day and made a bet to see who could drop their watch and run down and catch it.
The english men went first, so he dropped his watch and ran down and it was smashed.
then the french men went, so he dropped his watch and went down and it was smashed.
So the Newfie went last, he dropped his watch and went home had a shave and a shower came back and caught his watch.
When he came back up with it, the english man and the french man asked how he did it and the Newfie replied, "I turned the time back a half an hour".
