For those who are unfamiliar with longtime Dodger fan Bobby Crosby, you really need to know about him.

Crosby is the originator of the popular YouTube videos under the name ‘dodgerfilms‘ and although most of Crosby’s filming involves himself catching batting practice fly balls (something that I strongly discourage people from trying), he also captures key moments from almost every home game at Dodger Stadium from his season seats in the Left Field Pavilion, which he later posts on YouTube.

Every now and then Crosby stumbles onto a real gem, which is exactly what he did during the recently concluded Dodgers/White Sox series at The Ravine.

While shagging flies during batting practice, Dodgers ace Clayton Kershaw and Dodgers closer Kenley Jansen were apparently a little bored and decided to impersonate each other’s pitching delivery. The results are hilarious and, as you might imagine, Crosby’s YouTube video clip of the moment has gone viral.
