it really creeps me out. my mom and dad call each other "mom" and "dad" when they're talking to me about each other (like, "is dad out with the horses?" or whatever) but never TO each other.

my aunt's ex-husband remarried to a women 10 or 15 years younger, who happens to be a totally out of control by insanely wealthy cokehead, who calls him "Daddy". EW.
