The three men had always done everything together.
Mick arrived first, and when the mortician pulled back the sheet Mick said, “Yup, his face is burned up pretty bad. You better roll him over.”
The mortician rolled him over and Mick said, “Nope, it’s not Stew.”
The mortician thought this was rather strange. So he brought Paddy in to confirm the identity of the body.
Paddy looked at the body and said, “Yup, he's pretty well burnt up. Roll him over.”
The mortician rolled him over and Paddy said, “No, it’s not Stew.”
The mortician asked, “How can you tell?”
Paddy said, “Well, Stew had two arseholes.”
“What? He had two arseholes?” asked the mortician.
“Yup, we never seen them, but everybody used to say: There's Stew with them two arseholes.”
