If I'm twenty can I get my underage friends into an 'R' rated movie?

So my ID says I'm 20 years old when i got my permit even though I'm only 15.. But it was just a mess up on the makers part it's not like a fake or anything! So if I go to an R rated movie can I get my friends in too by using my ID? Because usually we just have a parent come in and buy all of our tickets. Thanks!:)
