In The Sunshine Boys, the character Willy explains funny to his nephew. “Fifty-seven years in this business, you learn a few things. You know what words are funny and which words are not funny. Alka Seltzer is funny. You say "Alka Seltzer," you get a laugh . . . Words with "k" in them are funny. Casey Stengel, that's a funny name. Robert Taylor is not funny.”
Scientist Richard Wiseman researched the "k sound is funny" theory in 2001. Wiseman performed an experiment to see if the letter k actually gets more laughs. It was built around a simple joke:
There were two cows in a field. One said, “Moo.” The other one said, “I was going to say that.”
Subjects were invited to rate random jokes from a database. In addition to the cow joke, Wiseman put several variations were included, i.e. mice that went “eek,” tigers that went “grrr,” and birds that went “cheep.” The winning variation, no surprise, had the most k's...
There were two ducks on a pond. One said, “Quack” and the other said, “I was going to say that.”
See, science proves that the k sound is funny.
