This happened just a few days ago. I (DM) recently had 2 people drop from the current campaign so while making adjustments to combat I threw in a few easy to win fights. Nothing major, a few giant toads, some crocodiles, etc. When the fight with the crocodiles happened someone described them as "murder logs" since their perception attempt only noticed logs.

Fast forward and the party quickly dispatched the crocs, and some inter party discussion started. One player is playing a warforge and was asking another if they wanted to take the crocodiles to cook for dinner since the other player had made a stink about not remembering to take the legs from the giant frogs to have for dinner. Asking if they were something people ate more than anything. This is what followed:

Warforge: don't you want to have this for dinner, since you eat.

Elf rogue: No see we can't eat those, see we can eat the frog legs because they are made of meat. These are made of wood, and elves and humans don't eat wood.

Warforge: they are made of wood?

Elf rouge: yes murder logs are made of wood and it isn't edible.

DM: you do know that they were really crocodiles right?

Elf rogue: yeah murder logssss...realization flashes in the players eyes...oh hell what was I saying, why did I think that they were wooden, I know they were crocodiles.

We spent the next few minutes laughing and everyone had a good time.

Not sure where the glitch came from but it was entertaining.
