ランダム riddle. a man walks into a bar and orders a ペリカン sandwich. he takes one bite and then goes out side and kills himself. Why

The man was in a ship that was wrecked on a desert island.  When there was no 食 left, another passenger brought what he 発言しました was ペリカン but was really part of the man's wife (who had died in the wreck).  The man suspects something fishy, so when they finally return to civilization, he orders a ペリカン sandwich, realizes that what he ate before was his wife, and kills himself.

I have no idea
