Two Goobers notice a couple of guys by a bridge.
The one guy drops over the bridge being supported by the other one holding his ankles.
After 5 minutes, the one hanging over the bridge shouts 'pull me up'.
His friend pulls him up and he's holding a 10lb salmon.
So one Goober says to his friend, "We'll try that."
Later, they come to a bridge and the one Goober drops over and the other one grabs his ankles.
After 5 minutes, the one over the bridge shouts 'pull me up'.
"Why, have you got one?" his friend enquires.
"No, there's a train coming" he replies.
