Hi guys. I'm trying to find this funny tv commercial that I saw quite a while ago. But I'm not sure what country it's from though, since I saw it on the news as one of the "world top funniest TV commercials of 2007" when I was in Japan last Dec 07. The tv commercial goes like this:

Guy goes home. Sees shoes & clothes & underwear strewn all over the floor. Barges into his bedroom. Wife is alone (naked I think?) on the bed, trying to look innocent. Guy opens the wardrobe and voila, half-naked guy is hiding inside there.

Guy looks at the hunky handsome muscular half-naked guy, looks at his own skinny wimpy body, then walks away dejectedly.

Punch line is something like: time to exercise / join some gym membership or something.

Any idea anyone???
Would be great if you could actually find this on youtube. Thanks in advance!
