Billy walks around Stormwind with Adam. Clearly he's pretty bored and trying to start a conversation, but Adam won't listen to any of his lies, comments, references or exaggerations:

"I heard that there are these huge fish that can walk on land to hunt, and eat people!"
"My daddy says that in the ocean, there are fish so big they could swallow a whole ship."
"I heard a story about this golden fish, and if you caught it you would get three wishes!"
"And one time, at camp, I caught a fish that was bigger than I am!!"
"I caught a big one last week, it had three eyes!"
"My daddy can catch more fish than your dady!"
"Look! Look! I caught something! Aww...it's just a stinky ol' boot."
"Think there are any fish in here?"

Eventually they say "C'mon let's try somewhere else" and move along, leaving you to fish in peace.

Adam is ace at replying though.
"If you fished as well as you talked the ocean wouldn't have any fish left."

"And one time, at camp, I caught a fish that was bigger than I am!!"
Clearly a reference to the American Pie movies, wherein Michelle, the marching band geek, always refers to her band camp memories with the introduction: "And this one time, and band camp, [...]".
