If you're really really wicked and uber cheap Slave Master Lent,
buy knockoff Pokemon cards for dirt cheap as prizes and don't
call it payment. They won't know they got ripped off until they
start trading in school (against the School Law) and their wiser
Pokemon Master buddies mock them for their Bad Trade with you.
Hope their starter Pokemon isn't Charmander or they might burn
your house down in vengeance tongue emoticon
