Sono l'uomo come il pipistrello
I had this sentence as a listening exercise and listened a few times, assuming I was hearing something wrong. I imagine the only normal context for this sentence is seeing someone at a costume party.
It's also line in the song "Parole Parole". It's a phrase that sounds weird out of context, but it's common in english and in context it makes sense. Could be "what star sign are you" or "what are you playing at" or "I'm a leader, what are you", or "I'm a security expert. what are you". Makes sense in context, without it, it sounds weird. Keep in mind though italians often use "which" or quale where would often use "what/che cosa".
