A mathematician asks an engineer a question,
"here are 5 birds in the tree, if i shoot one,
how many are left?"
the engineer answers, "0, since the birds will all fly away when they hear the gunshot."
"the correct answer is 4,
but i like the way you think" said the mathematician.
the engineer then says,
"well then, i will ask you a question.
three women are sitting on the park bench eating ice cream.
the first one is licking it,
the second one swallows the ice cream
and starts sucking on the cone, the third takes a bite out of the ice cream, which one is married?"
the mathematician blushes and answers: "the second one?"
the engineer then says, "wrong, the answer is the one wearing the wedding ring, but i like the way you think."
