I doubt if these exist anywhere on YouTube...but my original hometown market had a couple of doozies:
* In the 1960s, a guy in front of the camera on the Jefferson City CBS affiliate throwing play paper money up in the air and yelling, "Money! Money! Money! Go to Thrifty FI-nance for Money!"
* Just a little later, there was a restaurant along Interstate 70 in Columbia called the Interstate Pancake House. The two owners, Ken and Lonesome Del, brothers, had a series of spots, again, shot with one camera, with bad puns featuring, at the end, one of the brothers getting a pie in the face. Example:
One brother at a chalkboard: "Pi-R squared!"
The other: "No, pie are around"
First: "Pi-R squared"
Other: "Pi are messy" and a pie would go in the face of the first guy.
Columbia, Missouri being Columbia, Missouri, this actually became controversial. Not because it upset the Mathematical Sciences department at the University of Missouri, but because the University's TV station, an NBC affiliate, deemed the ads to be in bad taste. But the new UHF ABC affiliate in town said, "no problem! come on down!" and the spots aired there.
