Which animal is the best at barbecuing? 

The grilla.

So, this snake walks into a bar.

The bartender says, "How'd you do that?"

So, a miner and a chemist walk into a geology convention. They approach a table displaying a wide assortment of rocks. 

The chemist points in the booth's direction and asks the miner, "Which is your favorite? Cinnabar or cassiterite?" 

The miner thought for a moment and replied, "Either ore."
