Funny you should mention that...

Years ago, the old, old sitcom "My Three Sons" had an episode where one of the sons was playing psychological-type pranks (if memory serves, for a school project) on his father and "Uncle Charlie".

At one point, the boy(s) added a lot of sugar to the ketchup bottle. Then at dinner, they tried to hornswoggle Uncle Charlie into believing that the tomato crop was sweeter this year... and Dad looks right at them with a Don't-BS-Me look and says "Who put sugar in the ketchup?"

Only thing is, since then, it's not a joke. Amazing, and sad, how many food items have had sugar added to them, over the last few decades.
