Hacky Sack Day - If you don't kick that sack on the first Sunday of the month

If you don't kick that sack on the first Sunday of the month, you're gonna regret it.

I missed Hacky Sack Day and my sack came to my house and yelled, 'You're gonna regret it.'

My friend tried to skip Hacky Sack Day. Now he's in a sack jail.

I skipped Hacky Sack Day and got a sack tattoo. It hurts.
