I accidentally skunked a light lager a while back. It is skunked to about Moosehead levels.
I left the better bottle out on the patio table to settle for about an hour prior to racking. It was an overcast day, but I didn't think about the fact that clouds allow a lot of UV through.
A slice of lemon in the glass makes it drinkable.
I have never heard of anyone intentionally skunking a beer, though.
