Rate my 2nd joke on a scale of 1-10?

A man walks in to K-Mart and orders a pack of gum

and the cashier tells him he needs to shave

then the man walks out the door

2 seconds later he gets hit by a truck and dies on the scene

about an hour later another man walks in the door and buys a candy bar

the cashier again tells him he needs to shave

and sure enough, the man walks out the door and 2 seconds later he gets hit by a truck, he dies on the scene

then when its time for the cashier to leave the store and lock up a man walks in and said that he wants to by a shaver and some ice

so the cashier goes and gets it for him and takes the mans money

hands him the reciept and the man heads out the door

but the cahsier stops him before he gets to the road and says he gave him too much money

so he gives him back 3 dollars

then they both walk out on to the street and sure enough they both get hit by a truck

and they both die on the scene

but if you read this joke cloasly you will find out the reason on why you need to shave!!!! so go buy a shaver and shave! but before you do that answer this Question and say that i made you waste 2 minuets of your life!!! BTW i was trying to come up with a punch line but couldnt think of anything. i was really planning on comming up with a good joke lol.
