When a veteran infantryman would meet another veteran, the question would be asked: "Are you a turtle?". To which the challenged veteran would have to either reply "You bet your sweet ass I am!" or have to buy the challenging veteran a drink.
Marine veteran: "You bet your sweet ass I am".
Turtle: It's like being a walking house that eats lettuce.
:I got stuck behind some turtles, so I had to walk all the way around.
-Hahaha those damn Turtles!
