Three Turtles Walk Into A Bar...

One of the turtles goes over to a piano and starts playing it. The other two start singing along with the piano with amazing voices.

The bartender can't believe what he's seeing. He walks over to the two turtles singing and says "You guys are incredible! Where'd did you learn how to sing?"

One of the singing turtles stands up, points over to the turtle playing piano and simple replies "he tortoise"
