Turns out it’s a talking duck, which orders a beer.

The human next to him is flabbergasted, starts to ask but midsentence realizes he can’t even formulate his question “You, you’re a … but what… you’re a…” The duck takes a sip and says, “Yeah, I’m a duck, spent most of my life as a roofer.”

“A roofer?!?”

“Yeah, you know, we put shingles, tiles other roof things on roof places. You know, roofer?”

“But you could be in the circus!”

“The circus? Place with all the tents and what have you?”

“Yes! You could make a fortune!”

“Now what the heck is a place like that going to need with a roofer?”

(This joke is older than I am but I love it. Fun one to tell as you can give the duck whatever voice and however condescending an attitude you want. I've seen some great people tell this joke and really stretch out that conversation for nothing but the joy of the voice.)
