An old mortician in Oklahoma is getting ready to retire and has had a replacement doing an internship for the last year.
He tells the Intern that he is ready to do his first solo autopsy... "if you have any problems, come get me I have seen it all."
The young Intern goes in to do the autopsy and finds a Sooner fan that had been killed in a shooting. It was obvious he was a Sooner fan because he had Sooner gear on and had OU tattooed on his leg.
After disrobing the victim he starts to clean him up and noting wound marks. He then turned him over and kept washing him. He spread the butt cheeks apart and hears "Boomer Sooner Boomer Sooner"
This freaked the Intern out and once again he spread the butt cheeks apart and once again "Boomer Sooner Boomer Sooner"
He went to get the old Mortician and said you have to see this. The old Mortician said "there is nothing you can show me that I haven't seen before". The Intern said "you haven't ever seen this"...
The Intern spreads the butt cheeks apart and once again "Boomer Sooner Boomer Sooner"
The old Mortician shakes his head and says "A$$HOLES have been singing that for years".
