“Nitrogen Chips …. Goin Fishin’ for Sardine ….. Kryptonite Vacation”

The air in a bag of potato chips is actually nitrogen, not oxygen . . . it keeps the chips from going stale.

Sardines aren’t actually a species of fish. There are at least 22 different types of fish that are used to make sardines.

Kryptonite was invented by the people behind the Superman radio show in 1943, so Superman could just groan in pain for a few episodes . . . and the voice actor who played him could finally take a vacation.
