Gate travel via wormhole is one way. A person cannot go through the gate, leave it open, and then step back through it. The gate has to be stopped and then restarted from the opposite planet in order to travel back to the other end. The only thing thing that can travel two ways through the gate are radio waves (which the MALP transmits back to Earth).

When a person inserts their hand into the hanging shirt of someone leaning over, passing through the legs from behind, past the chest, and, ideally, reaching the pot of gold: the face, in order to sequentially tickle all aforementioned parts
