Duck Lipstick
/Riddle
Q: What did the duck say when she went to buy lipstick? A: Put it on my bill.
What's So Funny?
The expression "put something on my bill" means to charge something to one's account. The duck wanted to pay for the lipstick later. A second meaning of "bill" is the mouth of a bird, which is where a duck would wear her lipstick.
