From today's (UK) Observer newspaper:

Zoo creates a stink

Brussels sprouts fed to a zoo's 10 gorillas as a festive treat caused a stink for visitors. Keepers at Chessington World of Adventure in Surrey have had to take the vegetable off the menu after complaints about the smell. One said: "We gave them a feast on Christmas Day and Boxing Day when we were closed, but now we have re-opened they have had a change of diet."

So - it even happens to gorillas - sigh...
