"Snappy dresser" joke

I received this one from a girlfriend whose husband works at a mortuary.
This woman goes into a funeral home to make arrangements
for her husband's funeral. She tells the director that she wants
her husband to be buried in a dark blue suit.
He asks, "Wouldn't it just be easier to bury him in the black
suit that he's wearing?"
But she insists that it must be a blue suit and gives him a blank
check to buy one.
When she comes back for the wake, she sees her husband in the
coffin and he is wearing a beautiful blue suit. She tells the
director how much she loves the suit and asks how much it cost.
He says, "Actually, it didn't cost anything. The funniest thing
happened. As soon as you left, another corpse was brought in,
this one wearing a blue suit. I noticed that they were about the
same size, and asked the other widow if she would mind if her
husband were buried in a black suit. She said that was fine with
her. So... I switched the heads"
