Strange use of "baby daddy"

[Wilson Gray]

In three separate, parodic versions of Star Wars seen here and there
on the tube, Darth Vader says to Luke Skywalker:

"Luke, I am your _baby daddy_."


The use occurs in parodies. So, I assume that it's meant to be funny.
But I just don't get it. How does

"Luke, I am your baby daddy," i.e. "the father of your child"

come close to making enough sense, given that Luke doesn't have a
child, to parody

"Luke, I am your father"?

If Luke has a child and Darth, instead of saying what everyone
expects, that he's *Luke's* father, says, rather, that he's the father
of Luke's *child*, especially expressing that claim in BE syntax, out
of place, to say the least, WRT the manner of speech used in Star
Wars, then *that* would be funny. IMO, IAC.

Well, "different strokes," as they say.
