3 BLONDES,SOME TRACKS,AND A TRAIN

ONE DAY 3 BLONDES TAKE A WALK IN THE FOREST.
WHILE THEY ARE WALKING ,THEY COME ALONG SOME TRACKS.
THE FIRST BLONDE SAYS,THESE ARE BEAR TRACKS.
THE SECOND BL0NDE JUMPS IN AND SAYS,NO THOSE ARE DEER TRACKS.
OF COURSE THE THIRD BLONDE HAD TO PUT IN HER PIECE AND SAYS,
ANYONE CAN TELL THOSE ARE FOX TRACKS.
ALL THREE OF THEM WERE STILL ARGUING 10 MINUTES LATER WHEN A TRAIN HIT THEM
