Another similar to my first post on this thread.

Two sailors are eating their meal and tapping the weevils out of their hard tack biscuits. One sailor taps his biscuit and out fall two very impressive weevils.

His friend ask which weevil he would choose if pressed. To this he answers "why the big one of course".

To this his friend calls him a fool, "don't you know you must always choose the lesser of the two weevils"
