a guy you ask for when you make a crank call

Subjects of man-on-the-street interviews sometimes give Heywood Jablome as their name to reporters. If the reporter's a novice and if the newspaper's copy editor doesn't catch it, the name ends up in print, embarrassing the newspaper and the poor scribe who was gullible enough to scribble down the bogus moniker.

a fake name like Harry Bush or Dick Hertz

A covert name given; see ben dover.

a name given to hide a persons true identity

i actually met a guy named Haywood Jablomi. He's an older dude, maybe in his mid-50s, lives west of Chicago. What the hell his parents were thinking naming him Haywood I don't know. He said he's used to the jokes about his name by now, although he doesn't like them, he won't change his name. But his friends call him Woody.
