I just got my new Super Ego and Horizontal Brain Cell yesterday.
I eventually succeeded in getting the Brain Cell clipped into the Super Ego yesterday, amidst much huffing and puffing and swearing. (I'd never done that with my Vertical Brain Cell, and I just wanted to figure out how it worked.)
Now I can't, for the life of me, figure out how to unclip the damn thing from the bag without risking the destruction of one or both of them, the legendary undestructibility of Tom Bihn's bags notwithstanding. Is there a secret skill or trick involved in this process?
