Which Episode Game

Okay, time for a game. See how well you know episode titles. (And the "horsey episode" does not count!) If there is more than one answer, list as many as you can. Have fun!

In which episode....

1) did Mr. Mouth make his presence known?

2) did Carlos play his tuba?

3) did Hunter stay over at McCall's?

4) was McCall accosted by a guy named Tony.

5) was the action in a foreign country? different state?

6) was the call at Sporty's phone booth for Hunter?

7) did the camera fade 10 seconds before you wanted it to? (No right answer, just curious!)
