OK, kids - do NOT try this at home. Watch this extremely close encounter with a Great White off the South African coast - and no skipping ahead!. Besides, it's only about 90 seconds long.
One of Johan Potgieter's more memorable comments on the video: "I've swam and dived in some murky water but still amazes me how something so large can just appear and disappear before you're done pissing in your swimsuit." I think for me, the opposite would occur - it would go right up inside me and never come out.
