A whoopee cap is a style of headwear popular among youths in the mid-20th century in the United States.
It was often made from a man's felt fedora hat with the brim trimmed with a scalloped cut and turned up.
The latter of these is in reference to Jughead Jones of the Archie Comics series, for whom the cap was a staple.
Other notable depictions of the cap include the ones worn by Goober Pyle of The Andy Griffith Show as well as characters in the films of the Dead End Kids.
In addition, it also appears in modernized form made out of a knit beanie[8] on the television show Riverdale.
