Here’s a cartoon by Gary Larson copied from The Far Side Gallery 2 (the 1991 reprint), from which this entry was originally based. The caption is “Danny shows off his sheep’s brain“.
If you want a more detailed view of sheep’s brains you might want to watch this video of Gordon Ramsay and Hugh Fearnley Whittinsomething sauteing brains and sweet breads.
