Lethal, born David McCleary Sheldon, popped up at No. 31 on the Billboard Social 50, a chart that ranks the most active artists on the world's leading social networking sites. The rhymer made his chart debut after he launched a video for 'Pancake Rap,' on Nov. 30. The visuals showcase him rapping over Chris Brown's 'Look At Me Now' beat.

In the clip, he cooks pancakes in his kitchen and spits lines like, "Yellow cheese eggs/ White pancake batter/ Put a little bit of butter in the skillet when it starts to bubble flip it over with yo' spatula."

The bespectacled MC speeds through his verses in much the same way Busta Rhymes does on the original song. As a result of Lethal's quick raps and comedic visuals, the video has garnered more than 6 million YouTube views.

Fellow YouTube stars-turned-signed act Karmin got shine in the spotlight when they also remixed Brown's track. Karmin member Amy Heidemann rapped through the R&B singer's part, as well as Busta's and Lil Wayne's verses, while her fiance and bandmate Nick Noonan supported her by playing the piano.
