Some goofball said he was with a company called "D&D".  (Already sounded suspicious, but I let him keep going).  Tried to sell me a small display ad on a poster that promoted the Iowa Hawkeyes.  Didn't say what sports, of course.  Wanted me to buy a 2x3 ad for $540, which would include 25 mentions on a local radio station, too.  When I said "no", then he said this was the final spot on the ad (of course... everyone uses this tactic), and that he'd let me have it for 1/2 price.
