Two dogs walking through the woods, both get caught in bear traps. One dog
says, "We need to chew off a leg to get loose." The other dog says no way.
First dog chews off his leg, goes in to town, gets patched up by the vet,
and comes back a few days later. The other dog is still in the trap. The
first dog says, ""You need to chew off your leg to get loose." The other
dog says, "I already chewed off three legs and I still ain't free."
