Luke Donald hit a great shot out of a bunker for an eagle at the WGC Cadillac Championship and celebrated by doing the classic exploding fist bump with his caddie John McLaren. Only problem is, McLaren either has somehow never seen an exploding fist bump celebration, or is unsure how it works. So when Donald does the exploding hand gesture, there's an awkward delay before McLaren realizes what he's supposed to do. Or maybe that's just how he rolls, maybe the fuse on his fist is longer than Donald's.These guys have a lot of work to do to top Tiger and his old caddie Stevie Williams, but this is a start, at least.h/t Shane Bacon
