One day, a blonde was skipping on some train tracks singing “21, 21, 21, 21,…””
Along came a blonde who thought it looked like fun.
So she joined in and started singing “21, 21, 21, 21,” and then a train came.
The brunette jumped off the tracks but the train ran over the blonde.
The brunette got back on the train tracks and started singing “22, 22, 22, 22,…”
