wanna hear a joke? #2

a brunette is doing jumping jacks on some train tracks, and she's going "24...24...24..." so a blonde walks up and says "may i join you?" and she says "yes", so they both start going "24...24...24..." they hear a train coming, and the brunette steps off the tracks, but the blonde doesn't. the train comes up and hits her, killing her. the brunette gets back on the tracks and starts going "25...25...25..." until another blonde walks up and they both starts going "25...25...25..."
