Is it normal to vaccum crumbs from your bed with your mouth?

Does anyone else who likes to eat in bed or sofa use their mouth to sort of vaccum the crumbs that fell while you were going at it, even though you were being especially careful? Or do you just wipe them with your hands? If so, do you gather them to eat them? Or to throw in the trash? Or just clear the surface and send it all to the floor? Would you do it to someone else's crumbs? I don't think I would, as a rule.

I'm curious. I never thought of it, but I just caught myself mouth-vacuuming!! Lol XD

Am I normal? IIN??
