No star (or YouTube user) is safe from viral video parody king Dave Days. The 19-year-old web star has parodied Beyonce, Justin Bieber, and Miley Cyrus in the past, and this time around, he is taking on Katy Perry and her already hilarious 'Last Friday Night (T.G.I.F.)' video.

Days' parody is a sweet and very funny clip that chronicles the not-so-exciting adventures of a computer geek on a Friday night. The video kicks off with a friend calling Dave saying he missed out on the best party ever and he better have a good excuse. With that, Days takes us through his typical start to the weekend, which involves lots of social media and silly computer memes.

"Who am I kidding / I was watching videos  / Skyping everyone I know / Facebook stalking friends of friends / Who I think are hot / Poke / Tweeting things that no one cares / Tumblr cat gifs everywhere / think I'm cool cause of my hair / But probably not / Now I'm all alone / This Friday night / Do it all again / Next Friday night," Dave sings during the chorus of his 'Last Friday Night' rendition.

In addition to letting us in on his secretive nerdy activities on Friday, Dave, who is donning a 'Double Rainbow' T-shirt, also shares his series of fake party photos that he stages and poses for in his bathroom. He even has a semi-freak out in one part when his trust WiFi fails him. Oh, the agony!

Dave Days will be releasing part two of his 'Last Friday Night' spoof on July 9, and we honestly can't wait to see more from this adorably geeky kid. In the mean time, fans of the video can check out his YouTube channel, Twitter page and official website for more comedic goodies.
