Another dumb ad was the one for XRX copiers with the 1960's-look egghead peering into the copier saying, "Hey Ben! Come here! (Duh, I've never seen the inside of a copier before, look there's actually something inside!)".
A really nice one was the Mercedes C-Class with the lady whose eyeballs turned into hearts, the whistling teapots, the parking meter spewing out coins, etc. Very nice background music, too.
