Alias of Greg Jacobs, former lead of the Digital Underground, best known for their 1990 hit "The Humpty Dance". Best known for his wearing of a fake nose and glasses during performances for comic effect, and would often refer to this in his raps.
"Hey, remember that video by Humpty Hump where he said he was big like a pickle?"

"I always wondered what happened to Humpty Hump after the 90s. Why did he wear that thing on his nose anyway?"
