How about this true story song:

" He was going down the hill doing 90 MPH when the de-railer on his bicycle broke, He landed in the grass with the sprocket up his _ _ _
and his ____ was playing Dixie on the spokes" (fill in the blanks)

Dang that hurt, tried to ride my bike today and the de-railer came off locked up the back wheel ... lucky that the concrete broke my fall LOL

road rash on my knee, back isn't feeling all the great either. But sadly my bike is out to pasture more embarrassed then hurt
LOL
