The Train

A brunette was jumping up and down on a set of railroad tracks saying, "21,21,21." A blonde walked by, noticed the brunette, started jumping up and down on the tracks and repeated what the brunette was saying. The brunette heard a train whistle and jumped off of the tracks. The blonde kept jumping and saying, "21,21,21." The train ran over the blonde. When the train ended, the brunette jumped back on the tracks and started saying, "22,22,22."
