Three Ducks

Three ducks walk into a bar and have seats on three different stools. Two of the ducks are happy, the third is quite depressed.
The bartended loves ducks. He approaches the first one, a happy ducky, and says, "HI, what's your name?"
"Huey!" The duck replies enthusiastically.
"How's your day been, Huey?" The bartender asks.
"Great, I was slipping in and out of puddles all day!!"
The bartended smiles and moves onto the next duck. He leans on the counter in front of this happy duck and says, "HI, what's your name?"
"My name is Stewie!" the duck replies enthusiastically.
"How's your day been, Stewie?"
"WONDERFUL, I was slipping in and out of puddles all day!"
"That's great."
The bartender moves onto the third duck, the depressed duck, and he says, "Let me guess, after Heuey and Stewie, you must be Louie!"
"No," replies the duck. "My name is Puddles and I've had a shitty day."
