My version is to sneak around Camp Icarus or Port Atlantis and hide n00b guns, ammo, amps, etc. in improbable locations, and call out a treasure hunt. Another thing I do is sneak myself into a hiding spot somewhere where there's dozens of green dots on radar, and play the "Colder/Warmer" game, with the first to trade me getting a prize.
Things like that help make the newcomer experience a little more "human" and fun. Too many of us spend most of our time rooted to the spot in front of auctioneers or construction machines like deafmute zombie-bots.
