bouncing pigeons

ok, this question is seriously bothering me and i hope i get an answer to this. you know those flying rats that invaded all city’s some time ago and haven’t disappeared since then? well, they were seriously getting on my nerves the other day while i was in florence italy. i asked friends of mine what would happen if i would kick one of them (one of the pigeons, not my friends) and if i would break their rib cage. one of my highly intellectual friends said that, no, the rib cage wouldn’t break bc the pigeon would bounce. something about elastic in their meat or sth. IS THIS TRUE!? it would be soooooo funny. like: doing doing SMACK! i dunno. what do you think? i’m too afraid to try bc i’m damn scared of those things…so, help me out will ya?
