Lolo Lids are $15 plastic lids made to fit on top of a beer can that can then be attached to the generic looking coffee cup FOR DRINKING BEER ON THE SLY. The cup is also insulated to keep your beer cold, provided it was cold to begin with and not sitting in the trunk of your car for hours in the summer sun. Alternatively, just pour your beer into a coffee cup. That's what I do, and everybody in the office thinks I drink eight cups of coffee before lunch and four after.
Keep going for the Kickstarter video.
Thanks to Jason B, who drinks beer the way God intended: out of his cupped hands like a cowboy drinking from a stream. Wait -- what? That can't be right.
