So here the joke I be heard, but I don't get the meaning of it. Can anyone help me understand why is it the answer supposed to be funny?

Q: What did the duck say when she bought lipstick?

A: "Put it on my bill."

    The joke is a pun, a play on two distinct meanings of “bill”. One is the duck’s beak, its mouth, where the lipstick would be applied (where its lips would be if it had lips). The other meaning of “bill” is like “invoice” or “tab”, a listing of items purchased along with price, and a total cost to be paid. Since he’s buying the lipstick, the purchase would also be listed on this type of “bill”. – Dan Bron Nov 27 '17 at 13:24
  • Asking for prior research is rather harsh if the OP doesn't know that it is a play on words, and what particular word has a double meaning. +1 because it is a nice joke. – Mick Nov 27 '17 at 14:52
