That beer can sleeve is pretty slick. I've always just put the beer into a red cup or used a ginger ale soda bottle.
On another note, I was helping a friend change out the fork seals on his Magna. The snap rings were rusted in there pretty good and my ring pliers were just not up to the task and wanted to bend (don't worry, we tried the penetrating fluid and the whole 9). So I put the plier nubs into the ring holes, and then squeezed the teeth together with another pair or pliers. Got the rings to pop right out.
There seems to be less and less garden in this state.
