Nothing is funnier then a cockerel learning to crow! All my roos have acquired their grownup crows now, it's interesting how different breeds crow differently. I'm so used to it now, it doesn't wake me up anymore!
Try a lion learning how to roar. Now that is funny. Even funnier is when the lion is very sensitive and sulks when you laugh at him. He really was not that bright. One winter day he decided to lick the metal cage fencing. Just like a scene out of The Christmas Story except it was the King of the Jungle with his tongue stuck. Poor Albert. I miss him. Of all the animals I worked with while a zoo keeper he was my favorite.
