Beginning of a Bar Joke

While waiting for Mom to get out of surgery, I was sitting with my aunt and her mom, whom I refer to as Gramma, cuz she's just that type, ya know? At any rate, a commercial for March of the Penguins comes on the tube and I'm like, my usual excited, jumping up and down in my chair clapping my hands and squealing like I'm two, self. My aunt knows of my penguin obsession, but Gramma doesn't apparently. So, in trying to explain it to her, I say, "If I was told I only had three weeks to live and was granted three wishes, one of them would be to go to Sea World or somewhere and play with the penguins. You know, give me some fish, a coat, and some penguins. The peguins and I will get along fine, I swear." By this time, she's looking at me very strangely. I ask what's wrong and she says, "What do you want with a goat?" I laughed so hard, I almost wet myself right there in the waiting room. Which had terrible coffee, by the way. I got her corrected and she started laughing too, and goes, "I thought you said you wanted a fish, a goat, and a penguin...and I couldn't figure out what you wanted a goat for. The fish and the penguin I could understand..." and was lost to the giggles. So was I. I mean seriously: a fish, a goat, and a penguin? Sounds like the beginning to a really bad bar joke....

'A fish, a goat, and a penguin walk into a bar..."

You finish it. I'd love to see what you come up with. God knows, I'm trying to come up with some. It's just too good an opportunity to pass up. You know me, I simply cannot walk past an open door. Ask Grasshopper or Wendy. The stories they could tell you...but won't.
]I have too much blackmail.
