"Cheatin' Fool!" joke

Otis, Henry, and Tom were sitting in a bar discussing their
wives.
Henry started by saying, "
I think my wife is fooling around on
me. I went home the other day and found a hammer and a saw under
our bed. I think she is cheatin' on me with a carpenter!"
Tom answered, "
Ya, I think my wife is not faithful either.
The other day I went home and found a pipe wrench and some pipes
under my bed. I think she is cheatin' on me with a plumber!"
Otis then joins in and says, "
Well, if you think that's bad,
I've got one for ya. I went home yesterday and found a cowboy
under my bed.
I think my Lina is cheatin' on me with a horse!"
