"Golf accident" joke

Joe is teeing off from the Back Tees. On his downswing
he realizes that his wife Mary is teeing up on the Red Tees
directly in his way. Unable to stop his swing he nails it and
hits her directly in the temple and kills her instantly.
.
A few days later Joe gets a call from the coroner regarding
her autopsy.
.
Coroner: "Joe, your wife seemed to have died from blunt
force trauma to the head. You said you hit a golf ball and
hit her in the temple, is that correct?"
.
Joe: "Yes sir, that's correct"
.
Coroner: "Joe, I also found a golf ball wedged up her butt"
.
Joe: "Was it a Titleist Three?"
.
Coroner: "Yes, it was"
.
Joe: "That was my mulligan"
