Haha, I did this very same thing three days ago to my cousin's board. He just bought equipment and wanted me to help him set it up. I don't use stomp pads and had some old ones laying around the house so I asked him if he wanted some on his... We got to the resort and he started giving me shit about sticking them in the wrong place. He can't bitch much I mean, they were free!
Its like that old wheaties commercial "try it, you will like it."
