Meijer (or whatever local supermarket you frequent) is great.
24 hours.
Buying Red Bull and riding the Penny Ponies by the entrance is a good way to kill an hour.
Especially when you get to the level of hyper that you attempt to "race" the ponies.
Works best around 3 am.
Once, my friend Mary kidnapped 4 of our friends.
We drove them to Meijer, gave them each $2, and instructed them to buy us presents.
When they returned, we graded their gifts in assinine categories.
(Edible? 2 points. Orange? 4 points. Found in the checkout lane? Subract 2 points.)
And we gave the winner a t-shirt from our dorm that said:
"Who's Your Monkey?"
That was the best day ever.
I got some really cool presents out of it, too.
I still have the sign that says "DANGEROUS: NO TRESPASSING"
I starred in a short film called
Magnetic Personality. Check it out!
