Hi, just want to explain why I undid your edit on Shayne Topp's page as accidentally pushed submit before writing my explanation. Although Shayne's 1st full appearance was in Hand Bomb, he appeared in the Smosh Summer Games trailer which was released first :)
If you check the casting for "Good VS Surprisingly Good" and "Longest Staring Contest Ever!", Melanie Moat was NOT in any of the videos. Melissa Melancon played Ian's date in Good Vs Surprisingly Good and Stephanie Altholz played his date in Longest Staring Contest Ever.
Melanie Moat has only officially been in "Boxman Loses the Election" and "My New Emo Hair!"
