*The Grammar Wizard enters*
Actually, it should read, "Hey you, the malicious kid riding the skateboard, stop that now! Don't you know that skatboarding, in the mall, is wicked and potentially treacherous?!
*The Grammar Wizard exits*
*The Grammar Supreme Ruler Commander-In-Chief enters*
The sentence in question, although awkward, is grammatically acceptable. Regardless, the sentence is within quotes to indicate a speaker is talking and, therefore, does not have to be grammatically correct.
*The Grammar Supreme Ruler Commander-In-Chief exits*
Anyway, I see that my feeble attempt at satire has been overshadowed by our not so subtle disagreement of proper word usage.
Yeeeeeehaaaaaaaaaaaaaa!
