What happens to Max and Kevin when they are walking to the millpond to see the fireworks?

It's the Fourth of July, and Kevin and Max are heading off to the millpond to enjoy the fireworks. Unfortunately, their fun is interrupted by Tony D, the town hoodlum. Drunk out of what remains of his mind, he approaches Kevin and Max, yelling all kinds of abuse at them. He also asks them if they have any M80s, which are super-powerful fireworks. Such fireworks would be dangerous enough in anyone's hands, let alone those of a violent, drunken gangster.
Not surprisingly, Kevin and Max don't oblige. For good measure Kevin calls Tony D a cretin. Not only that, but he actually explains what a cretin is, because, well, Tony's too much of a cretin to understand what it means. Anyway, Tony gets mad at this outrageous, but completely accurate, insult and starts threatening Kevin and Max with a knife and shouting "It's freak-show time!" He chases the odd couple—with Kevin still perched on Max's broad shoulders—into the millpond, where Tony gets stuck. Looking like an even bigger idiot than normal, he has to get his fellow gang members to help him out.
The police arrive in the nick of time before any more nastiness can happen. It's been a strange old night, to the say the least, exciting and scary in equal measure. It's also brought Kevin and Max even closer together. From now on, they are to be known, at Kevin's insistence, as "Freak the Mighty," a humorous reference to Max's strength and Tony's insulting reference to Kevin's disability.
