4, 3 & 2. Mamrie Hart, Hannah Hart, Grace Helbig
YouTube Channels: YouDeserveADrink, MyHarto, YourHarto, DailyGrace, graciehinabox There are no girls funnier than these three when they get together. Mamrie Hart has a series called "You Deserve a Drink" in which she fixes alcoholic beverages. But it is not just a video where she makes drinks, no, she has a joke-per-second style to her videos that will have you laughing constantly. Hannah Hart has a series called "My Drunk Kitchen" in which she prepare food and cooks dishes while drunk. She is very funny and can make more puns than you can imagine. Hannah just might be the queen of puns. Everything she says has me rolling on the floor laughing, and I highly suggest you check her out. Grace Helbig posts to her channel "DailyGrace" every week day. She has a certain theme for four of those days, and every video makes you laugh out loud. You would think that posting five videos a week, none being scripted, she would run out of ways to be funny, but she doesn't. These three are the hilarious together and will make you laugh all day. They also are branching out of YouTube as they are currently shooting a movie. These three have everything it takes to be a success, and it looks like they are just starting on that road to glory.
