along the lines of... hippo goes out into the bush, get shot with a sedative gun right in the neck and down he goes. While he's asleep the conservationists put a tagging device on his head and to stop him being killed for his ivory they remove his tusk.
He wakes up next morning not sure where he is, wanders around to get his bearings and makes his way home. Well missus hippo is livid, "where have you been all night?" he slurring his words from the sedative says he's not sure...she says "you've been out boozing all night, and where's your horn gone?.. you've swapped it for that big dish on your head...".. stunned and shocked he turns slightly... "is that a love bite on your neck?"....
