Maccas Skiddy
To pull a maccas Skiddy, feed you kid (works best with kids under 3) more than the recommended amount of chicken nuggets. Then force feed them some lacitives until they shit themselves. Let them outside to play on the slide. Make sure you tell the other children your pouring chocolate down the slide proceed to release your child and let them spread there runny shit all over the playground. Those kids will then get diarrhoea due to eating the said chocolate, then they will also shit all over the maccas playground. This will cause a mega Maccas Skiddy. This could lead to a town wide spread of the maccas Skiddys and could cause a catastrophic crash of the maccas market. Hot fudge will also be free.
When I was six I cause a mass maccas Skiddy and I'd do it again.
