a joke i heard before..i think its funny

an old man turns 80 today. he decides to go buy a gt500. while out riding around a state trooper comes up behind him and hits the lights. knowing the old man's in a 500 he says to himself, " theres no way he can keep up with me." so he nails the throttle. after hitting 160 he comes to his senses and pulls over. the cop comes up and says" i end my shift in 15 minutes, if you can come up with a story that ive never heard before ill let you go." The old man looks at the cop and says," i lost my wife 2 years ago to a state trooper and i thought you were trying to give her back!"

Thats a good one
