I think everyone knows this, but if ya don't it'll help ya out.
If Abe is standing at a health vendo and munch is somewhere else and in need of life you can drink it for him!(Or vice verca.)
Just press A at the vendo and quickly switch to the other guy(With BLK) and you'll see the replenished health birdies flying over his head!
Wait...I got another one! I've had a possesed slig drink outta a couple vendos. Expresso, Invisible and Health.
