First off, nice theme Aizuke. BoA is awesome. =D
I've seen quite a few annoying commercials in my life time(ie. ZOOM ZOOM ZOOM!), but there have been some hilarious ones. For example, the Pepto Bismol add where this woman is calling the 'hotline,' saying that "Rex ate too many dog biscuits." After the guy on the line says that they don't treat dogs, she says "Oh no, Rex is my husband." I lol'd when I saw that for the first time.
Though like all commercials, it gets old after you see it a dozen times or more. Heh.
