A study said Most American car horns honk in the key of F???

Are you sure it didn't say "Most Americans honk their F-in' car horns...;-)"

My mate Mike used to tune his guitar to the pitch his window vibrated at when a large vehicle went by. Didn't take him too long as he lived on a main road but he was a bugger to play along with - we never did find the key!
