99 Bottles of Beer on the Wall (Challenge)

99 Bottles of Beer on the Wall is a recurring challenge involving speed and tribal cooperation, originating in Survivor: Hawaii.

Rules
Every three/four turns, one tribe member will "sing" (actually type) the lines of "99 Bottles of Beer on the Wall" until there are "zero" bottles on the wall. Each of the four representatives may only edit their "bar" every four turns. First tribe(s) to reach the zero line (or to have the longest lyrics before the deadline) wins immunity.
