"Nice dog. What's its name?" I asked my friend's 10-year old son.  

"Bob," he said.  

"And what's your cat's name?"  

"Bob."  

"Well, how do you keep them straight?" I asked.  

"Well, one is Bob Cat and the other is Bob Barker," the boy answered.  

"Go ahead and tell him your rabbit's name," his father suggested.  

The kid smiled and said... "Dennis Hopper."
