Two blonds hunting...
Two blondes were walking through the woods when they came upon a set of tracks, the first bloned said, oh look those are deer tracks! the other blonde just laughed at her and said, don't be stupid those are bear tracks! The first blonde said you must be kidding me, those are deer tracks! Bear tracks, deer tracks, bear tracks, deer tracks, they argued back and fourth until the train came through and ran them both over.
(any blondes reading this, they were Train tracks!)
