I love Katy Perry's song, Last Friday Night (T.G.I.F.)! It is a fun song to listen too and I think her music video reflects that. The neon 80s-style clothing helps add to the fun atmosphere of the video as well. If you haven't watched this yet, I think you will find Katy very funny as she plays a slightly nerdy character with glasses, braces, and head gear. The video also features several famous people which include Youtube sensation, Rebecca Black (who sang Friday), Jazz musician Kenny G plays a solo on the sax while the pop band Hanson plays along side him, and "Glee" stars Darren Criss and Kevin McHale.
