K2 didn't just "give them to him out of the kindness of their hearts," it wasn't like a gift because K2 cares so much about everyone. They were a promotional item, for people who SELL a lot of K2 products. K2 is making bank off of their stuff and they don't give a shit what someone does with a pair of their Brewskis, they are just a promotional tool to get their name out there and collect some extra cash for advertising for Pabst. Use them, sell them, trade them, throw them in a wood-chipper, I guarantee you that K2 doesn't give a flying fuck because they already got paid. This dude got the skis, he can do whatever he wants with them. Be careful trying to sell them here though because people are going to give you a lot of shit, at least they have to the other guys, but they were asking insane prices like $800. My recommendation is to take them to TGR or to Ebay and you'll probably get enough cash to get a regular pair of Seths and have some money left over, but don't expect anything crazy.
Oh, and to clear things up, the "Brewski" is just a graphic, it was pressed on some Maidens and some Seths and probably some other skis. If you compare pics of these and the other 2 pairs which have been up for sale here on NS you will see that the dimensions are quite different.
