Why Doesn't This AppleScript Work?

[nstahl2124]

set the alert_message to "Connor, your fat ass is about to get so butt ****ed that you don't even know what the hell is going to happen."
display dialog the alert_message buttons {"**** Me", "Awee Hell No!"} default button 1
set the my_choice to the button returned of the result
if my_choice is "Yes" then
    tell application "AppleScript Editor"
        shut down
    end tell
else
    delay time_amount * 10
tell application "Finder" to shut down
    end tell
end if
continue quit

I wish to put this on my computer since my friend's brother when he comes over he will not get off the iMac when we want to use it.
