'Mad Libs' plus 'Fifty Shades' is always going to bring filth so you have to hand it to Dakota Johnson for keeping it PG.

Johnson and 'Fifty Shades Darker' co-star Jamie Dornan will be popping up everywhere in the next week ahead of the films release on January 10th and last night was no different as Johnson made a 'Tonight Show' appearance that allowed Fallon to make the most obvious jokes about 'Fifty Shades' in the form of some 'Mad Lib Theater'.

Johnson, for her sins, goes along with it and enjoys the ride but we'd pay good money to never have to watch Jimmy Fallon try and be a Christian Grey ever again.
