History what the hell is a Leaping Lena?

Found two of these bodies holding a tin roof in place. The old man made me buy a Ginger Ale before I could take any pictures.

 

looks like cars from an amusement ride??????

 

they may be holding the tin roof down , but what is holding the building up? it looks ready to fall down, those bodies will be easy to get to then

 

Ditto on that...from an old carnival
or amusement park ride.

Ironically enough, a Leaping Lena is what you have as an avatar. They are parade or circus wheelie cars, usually Model T based with an extremely short wheelbase
