fat guy preparing a romantic bathtub?

weird title aside, from when i was younger i remember an ad of a chubby man preparing a romantic bathtub with rose petals candles etc. The man then steps one foot inside the bathtub and i think his other foot slips leaving him in an awkward position, then i think his wife opens the bathroom door and the man's crotch is obscured by a camera angle behind the wife with her arm on the doorway. I don't remember if it was an ad or a scene from a movie, if anyone can find this wierd scene ingrained in my head that be great, it should be around the mid to late 2000s, from when i was a kid
