'Tonight Show' host Jimmy Fallon's obsession with trucks -- and buying one this week, thanks to his Fingers on a 4x4 contest -- has seeped into every corner of the show over the past few days. As such, this week's round of "Tonight Show #Hashtags" was all about finding out viewers' worst cars. Oh, Jimmy, that's just mean!

As is often the case with Fallon's hashtags, there are some big hits and some minor misses -- but when he gets to a true gem, there's no question that the gag is worth it. Maybe next week he'll ask everyone to share their best car ever? Or maybe he'll be too busy with his own new car to care?
