oak park orgy
an orgy in oak park that needs at least 3 people, and one of them has to be either a donkey or a platypus. you also have to do the niebergall, or you're not even at the party.
the platypus showed up and did the niebergall. no one knew what to do.
i brought a donkey and it just sat there. it didn’t do the niebergall.
the OPO was awesome until someone forgot to do the niebergall. now it's a legend.
