2 Hunters

An avid duck hunter buys a black Lab that can walk on water. Sitting in     
the duck blind with good friend, Cletus, a flock of ducks flys by and 
they fire several times.  Several ducks drop. The dog "pitty-pats" across 
top of water and retrieves them.  Cletus is noncomittal.  This happens 
several times and dog owner is antsy at no response from Cletus.  

When he can stand it no longer he says, "Damn! Clete! You blind?  Don't you 
notice something about my new dog?"  

Cletus shifts his Red Man to the other cheek, spits and says, "Yep.  
I noticed he cain't swim!"
