If you’re going to be preoccupied with songs about beasts of burden, you might as well have the stage banter to go with it:
During WWII, a work crew was assigned a mule to haul loads for them. At least they thought it might be a mule. They debated whether it was a mule. Or a donkey.
As the debate continued, their chaplain walked by. They decided to ask him: “Father, is this a mule or a donkey.”
The chaplain replied, “Well, according to the bible, it’s an “ass”.
Years passed, and the beast finally died of old age. The men were out digging a huge grave as two WACs walked by. They asked the men, “Are you digging a foxhole?”
To which the men replied, “Well…not according to the bible.”
