How many times have you heard the rule about genies: you can't wish for more wishes. Kids always think they are the first to think of this loophole. Barring that, they are going to look for other loopholes! This comic is from Buttersafe. Link -via Daily of the Day
I'm sure the genies invented the rules for a reason, and that reason is past experiences.
Maybe one who breaks the rules of the genie gets into the lamp instead of the genie, and every time someone breaks the rules the cycle is broken and a new genie is born while the old one goes free.
A Doctor Who theme anyone? No? I'll show myself off.
