Walk this way (humor)

"Walk this way" is a recurrent pun in a number of comedy films and television shows. It may be derived from an old vaudeville joke. It refers to the double usage of "way" in English as both a "direction" and a "manner".
One version of this old joke goes like this: A heavy-set woman goes into a drug store and asks for talcum powder. The bowlegged clerk says, "Walk this way," and the woman answers, "If I could walk that way I wouldn't need talcum powder!"

Marty Feldman, who played the hunchback Igor in "Young Frankenstein", later said: 
The Aerosmith song "Walk This Way" was inspired after the band went to see "Young Frankenstein" in 1974.
