Each morning a group of 5 young males cross the lower Zambesi to reach an island covered in reeds with succulent roots. The elephants use the trunks to pull up a cluster of reeds and then pound the roots against their legs to knock off the dirt. At the end of the day, they return to the mainland. Note in this video that they stop midway across the channel and look to be doing some male rough-housing. When they climb out of the water, note that one helps the other up the bank with some head nudges. Also note that they climb out on their knees before rising.
