"We want" --> "I want" is probably at least true. Or, at least there's the "we're pregnant" thing, in which case I'm pretty sure the man actually isn't pregnant.
I think a comedian wrote a book and dedicated a chapter to that (I saw a quick glance, but there was everything the woman did as "we did" - I really want to read it, it annoys the heck out of me when they say "we're pregnant"
)
