Of nieces and nephews

Have you guys heard this joke?

There was once was a father-to-be who had an absolute moron of a younger brother. As in "Dumb & Dumber" kind of stupid. Anyway, on the day his wife went into labor, the guy couldn't make it in time, so he didn't have a choice but to ask his moron brother to accompany his wife to the hospital.

By the time the father, got to the hospital, his wife had already given birth, to twins no less. A boy and a girl.

Moron younger brother then told older brother that he took the liberty of naming the babies. Filled with trepidation, the father asked him what he named them.

"I named the girl 'Denise,'" younger brother said.

Hey, that's not such a bad name, older brother thought with relief. "And what did you name the boy?"

"De-nephew."

Har har har.

The point behind this joke -- I just came from getting an ultrasound... and we're having a de-nephew.
