Anyway here are their best 3 parodies, and what better way to start it off than with the one that started them off, a parody of TIK TOK by Kesha, where she even comented on the song saying "holy. shit. this is better than my version."
Now for my favourite parody of theirs, a parody of Katy Perry's ET:
And thirdly their parody of down. whrere Jay Sean comented "Hahha brilliant"
Another good parody by them is their parody of All time low-the wanted and friday-rebecca black
Like i said they are amazing, and pesonally i find their actual songs better than their parodies, so here's a link to their wiki-page, with extra information on their songs and stuff, like the new book they released and the idea of an upcoming sitcom?
