Top Ten Favorite Celebrity Guest Stars In Cartoons

Quite a few cartoons have celebrity guest stars with some being used well and others being used poorly. I will listing my favorite celebrity appearances in cartoons. Here are my top ten favorite celebrity guest stars in cartoons. Before I get to the list I want say a few rules. Celebrities can't be voicing themselves. They can't be too important on the show like John DeLancie as Discord (MLP:FiM) or Patrick Stewart as Avery Bullock (American Dad!). No Adam West because he appears in way too many cartoons for him to feel special anymore. Also, only one character per show. Now on to the list.

10. Lou Ferigno as Billy The Hero (Adventure Time)

9. Neil DeGrasse Tyson as Waddles (Gravity Falls)

8. Snoop Dog as Street Dogg (Sanjay and Craig)

7. Michael Jackson as Leon Kompowsky (The Simpsons)

6. Ringo Starr as The Duck Brothers (Courage The Cowardly Dog)

5. Andy Samberg as Colonel Carper (Spongebob Squarepants)

4. Wanda Sykes as Shirley B. Awesome (Penn Zero: Part Time Hero)

3. Stephen Colbert as Zeep (Rick and Morty)
