Lou reference in New Vegas?

[NicolasExposition]

I was playing the mission for the king where he tells you to go talk to his friends in Old Mormon Fort, and the guy mentions someone named Lou, lieutenant. The other guy says he's as dumb as a mutant. Anyone think this is a reference, or just a coincidence.

It's a reference, yeah.

Guy1: Now that I think about it. One of them said a name. Lou? Lou something?
Guy1: Lou Tenant, that was it!!!
Guy2: He probably said lieutenant. You'll have to excuse me friend, he means well but sometimes he's dumb as a super mutant.

It made me lol because I love Lou Tenant.

But New Vegas has way too many needless Fallout 1/2 references/cameos.
