>One of the bits that Jimmy Fallon does on the Tonight Show is an interviewer who asks people a question but uses nonsense words that sound "right" in the question.

There was a similar thing going around the Japanese Web a few years ago, where you'd try to sneak in soundalikes into conversation without anybody noticing, but the example I remember vividly was replacing "irasshaimase!" ("welcome!") with "ikakusaimase!" ("it stinks of squid!").
