Lionsgate have just after releasing this extremely not suitable for work trailer for Dirty Grandpa, a buddy road trip / fish-out-of-water comedy featuring Zac Efron cracked off his nut and Robert De Niro, who's recently become widowed and is on a mission to bed Parks and Rec's Aubrey Plaza (you may not recognise her with all the tan) in the most unceremonious fashion imaginable.
Dirty Grandpa hits theatres stateside on January 22, 2016, and also stars Zoey Deutch, Julianne Hough, Jason Mantzoukas, Danny Glover, Adam Pally, and Dermot Mulroney.
