"Where's my snare? I can't hear my snare..."

•firstly, who the hell decides ta keep such things and engineer-related utterings as adlibs?
arer these strictly limited ta self-aware R&B and Rap artists, or has this eventing also reared it's head in any great embarassing Rock-star moments as well?? I could imagine sumbuddy like the leadsinger of Warrant asking ta "turn up my headphones" before fully enaging in the forthcoming tear-evoking lighter-wafting Power-ballad.

•secondly,-why did Eminem's hilariously strange askings of where his snare might be (esp on such an embarassingly deathly serious song)--why did that not then catch on as a cultural catchphrase phenomenon??
Dudes, that right there coulda been our "MORE COWBELL!!". ...dudes, I'm sayng, we might've missed our best chance...

but yea, what's the deal with the every once in a while random bits of intentional un-edited out studio-talk that makes it past these super-professional releases? maybe this's ta mystifyingly "bring you right there in the studio"?? maybe they just think it sounds hot?
