A few years ago, McDonalds tried to have their spokesclown appear more adult by going out dancing and stuff.

I think that was when they were launching their salads or something. Anyway it quickly went away, as will the cheeta who sepearates whites at the laundrymat. Though the new ads do appear to have a lot of work put into them for being so laughable, which falls in line with the cat's old mantra -- It ain't easy, being cheesy.
