Judge which joke is funnier

Tell me a joke about an archaeologist and a duck.

Joke A

Why did the archaeologist bring a duck to the dig site? Because it was an expert at "quacking" ancient codes and could really "bill" out the historical details!

Joke B

Why did the archaeologist take his duck to the excavation site? Because it had a fowl temper and was great at digging up dirt on the past! (get it?)
