Actress-singer Anna Kendrick is somewhat notorious for making filthy (hilarious) jokes on Twitter and is overall really charming.

Her most recent appearance Tuesday night on CBS' "Late Show with David Letterman" only continued to make that the truth.

When trying to move onto something else, the 29-year-old Kendrick could not help but tell the 67-year-old Letterman what an item from a previous bit -- a cat toy -- actually looked like.

She said it resembled instead something for adults. Her comments visibly caught Letterman off guard, but were quite an accurate observation, honestly.
