Ask your husband to read the following passage from Leviticus.
11:13 And these are they which ye shall have in abomination among the fowls; they shall not be eaten, they are an abomination: the eagle, and the ossifrage, and the ospray,
11:14 And the vulture, and the kite after his kind;
11:15 Every raven after his kind;
11:16 And the owl, and the night hawk, and the cuckow, and the hawk after his kind,
11:17 And the little owl, and the cormorant, and the great owl,
11:18 And the swan, and the pelican, and the gier eagle,
11:19 And the stork, the heron after her kind, and the lapwing, and the bat.
Then ask him if he thinks bats are a kind of fowl.
"I know some of you are going to say 'I did look it up, and that's not true.' That's 'cause you looked it up in a book. Next time, look it up in your gut."
