Bands' nicknames for producers/egineers

[-J-]

What's up with all the nicknames that bands have for producers and engineers in their thank-you lists? When I meet someone I don't typically immediately give them a nickname, but it would seem like nearly every band thanks producers/engineers as First Name "nickname" Last Name (i.e., Andy "Undie" Sneap by Megadeth). I don't quite get it - is the producer in on the gag all along, or do they just sort of add it behind their back and hope they play along?

I'm sure some of you have some shining examples....bust 'em out!

It is like a requirement for Finnish metal albums. Especially those produced or mixed by Mikko Karmila. He's probably the Man of Thousand Nicknames

Recorded at Tico Tico Studio, by Ahti "Viheltääääääää...khh khhhhhh!" Kortelainen during March, April and June 2004.
Mixed at Finnvox Studios by Mikko "Hevikabaree???" Karmila.
Mastered at Finnvox Studios by Mika "bluelight" Jussila, June 2004.

"Bombs away! KSCHHHHHHHHH"
"Heavy cabaret?"

Recorded at Tico Tico Studio by Ahti "onneks ei olla ens levyn biisejä soittamassa" Kortelainen
Mixed at Finnvox Studios by Mikko "intialaisetkin voi innostua täst musasta" Karmila, while Tony and Marko drank coffee.

"Luckily we're not doing a debut album"
"Even the Indians could get excited about this music"

"undie" is because of Andy's accent i think

Thats what I thought too. And it's also kinda funny so I don't think Andy's gonna have something against it
