My grandfather has the heart of a lion and a lifetime ban from the Zoo.

One word for this one - crafty. Much like the way a lion stalks its prey, or an American man stalks a red lobster diner, this one catches you when you least expected it.

• 50/50 if this is Puntastic or Pundiful

• Bluntness - 5/5 - Only a well-versed Al chatbot can surpass this one on the bluntness scale.
