Move a letter, make a new word -- game

Whether it’s ever been authenticated or not, there was speculation that HAL, the computer in 2001: A Space Odyssey was just an acronym formed by moving the letters in IBM one click to the left: I-H, B-A, M-L.

Let’s move some letters that way and make some new words. Minimum of one letter moved as in Zod to Zoe, maximum of all letters moved. Duh! No moves further than one letter’s worth. Either direction is okay, even mix and match.

Kerry – Lessy
Jump – Juno
CPU – BOT

Who can make the funniest one?
Who can make the most “gee whiz” one?
Who can make the longest one?

Who can link to the thread(s) where this has already been done?
