A: You can wait until you get older. But who has the patience for that?
I suggest drinking out of this can I have here in my brown paper bag. It's a good old fashioned growth serum. Tale a sip.
Yeah, it sure does burn. That means it's working.
How about you go lay down behind that dumpster? You might feel woozy while the serum takes effect.
And you should probably take off your pants. Wouldn't want them to get ruined by your sudden growth spurt.
