This is from "Bad Kiss" S3 E39

So Margaret, let me get this straight. You hang out with Mordecai, walking down a street with Rigby and Eileen. A food vendor comes by and drops a chili dog. Without hesitation, You watch Mordecai eat said chili dog OFF THE FLOOR. Later on, you find Mordecai inside your car. You lock eyes with Mordecai and proceed to kiss him. So after 5-10 seconds into the kiss, now you are surprised he has bad breath?!

In the words of the late Peter Cullen: LOVE STINKS. I must be missing a key detail somewhere.

The best episode of season 5!

Without the horrendous disc packaging getting in the way of what you should expect from this
