Mama elephants sometimes spank their babies with their trunks, usually one or two swats. I saw it on the Discovery Channel the other day. Then, PETA intervened citing animal abuse. J/k...PETA doesn't get involved in elephant-on-elephant violence.
Also, "teen" (or "allomother") elephants babysit younger elephants. I wonder if they ever say, "But moooooom....!"
