I used to always have my wall-to-wall carpets cleaned by a dude in a bright yellow van. Back during the dinosaur days, the company ran a TV commercial with a clever jingle I never forgot. A big, burly dude with a mop of unruly hair and a bushy mustache was the voice for the ad. It went something like, “If the van ain’t yella, ya got the wrong fella.” Geez, was that little ditty prophetic.
