hmm I think u mixed two soties there..
vale once climed on a chair (that was standing on an other chair or a table, don't remember..) to get to a plate with sweets uccio was holding the chair.. but couldn't, so vale fell and broke his arm...
that'S from the uccio interview..
then in his autobiographie he describes I think, 2 crashes with his ape car
but there he didn't hurt himself, if I remember corectly
he once broke his ankle when he was hit by a car while he was riding with a friend on a scooter, on their way to the beach..
never heard the story about the van and the buns thoug..
about the scar on his chin.. no idea where it's from.. maybe a shaving accident
the same with the scars on his elbows.. no idea...
