That's an... interesting costume you have on.  Even though you're being nice and helping a sick child trick-or-treat this year, I'm afraid I'm going to have to ask you perform a trick for me!$B$BLet's see... you look so strong and buff in that... costume... let's see you flex!  Yes, go on now and flex for me, strong $g man : woman;!$B$BWhen and only when you flex, I'll give you some tasty Orgrimmar Nougat.  It's a great Hallow's End treat.
