Aaron Paul -- Yeah, I'll Sign Your METH BEAKERS!

Prepare to be jealous Breaking Bad'ers -- cause a few guys at LAX got Aaron Paul to sign their meth beakers, yo ... and we got the dope footage.

It all went down at LAX -- where the autograph seekers swapped out the usual stack of headshots for the meth paraphernalia -- and Jesse Pinkman was cool enough to sign.

Paul also talked about the Walter White obituary that ran in the Albuquerque Journal ... telling us he actually felt bad about it ... 'cause it may have spoiled the ending for people who hadn't seen the finale.

BTW, this video features "Breaking Bad" spoilers ... but nothing you haven't already read on the Internet. Sorry slackers, you gotta catch up.
