Guessing games

Once there was a family who was given some venison by a friend. the wife
cooked up the deer steaks, and served it to the husband and children. the
husband thought it would be fun to have the children guess what it was that they
were eating.

is beef? the daughter katie asked.
nope.
is it pork? the son willie asked.
?nope.
?heck, we don't know, dad! willie exclaimed.

i'll give you a clue, the dad said, it's what your mom sometimes calls
me.

?spit it out, willie! cried katie, we're eating a******!!
