Not counting explicit profanity like "fuck" and "cock".
1. Angry Unpaid Hooker - TV-14-DS (Original rating)/TV-14-D (Current rating) - Debbie giving Tim a lapdance isn't very strong, so it doesn't earn an S.
2. Rodney's Bachelor Party - TV-14 - Frequent mentions of rape, but it doesn't earn a D. And one use of "shit" doesn't get an L.
3. Latino Tim - TV-PG-L (Original rating)/TV-PG-DL (Current rating)
4. The Priest is Drunk - TV-14 (Original rating)/TV-PG-DL (Current rating) - Tim squeezing an elderly woman's breast doesn't get an S.
5. Senior Prom - TV-14 (Original rating)/TV-PG-DL (Current rating) - Originally for the boss' daughter getting Tim to spank her butt, but it's not enough.
6. Tim Fights an Old Man - TV-14-L
7. Mad Dog Tim - TV-14
8. Monday Night Confession - TV-14-DL (Original rating)/TV-14 (Current rating) - Infrequent mentions of handjobs and masturbation, so it's fine without a D. Also, two uses of "shit" doesn't earn an L.

10. Miss February - TV-PG-DL (Original rating)/TV-14 (Current rating) - Just for Debbie mentioning "B.Js".

12. Tim's Not Singing - TV-14
13. Hottest Babes on the Planet - TV-MA (Original rating)/TV-14-DS (Current rating) - Originally for pornographic images inside a cubicle, but it's shown briefly, so it should be fine.
14. Suck It Philly - TV-14-DL
15. Insurmountable High Score - TV-14 - I could rate this episode TV-PG-LV if "shit" wasn't said once.
16. Tim vs. the Baby - TV-14-L - A woman's breast being exposed isn't an S.
17. Mugger - TV-14-L
18. Cin City - TV-14 - I was going to re-rate this episode to TV-PG-DL, but one mention of blowjobs earns the rating.
19. Theo Strikes Back - TV-PG-DL
20. Amy Gets Wasted - TV-14 - Just for a penis-shaped hat being shown.
