Man: Nighthawk this is acrobat! Area has been sterilized! Man 2: Roger, acrobat! Roland: Sterilized? Good god! Should I tell the others? Mr. President! George Bush: Yes Roland Roland: Sir. As you know, there's been a lot of talk recently about a secret society you belong to at Yale. It's said that the group was behind the recent theft of of Martin Van Buern's skull. It's said that it's members have guaranteed lifetime incomes. There're rumors of ritualistic nude wrestling. Of course, none of these stories is verifiable because no member has ever broken the society's code of absolute secrecy. In fact, the code is said to be so strict that members are required to leave the room if any outsider so much as mentions the group's name, skull and bones! Sir, would you care to put to rest these... Man: Excuse me. Mark: Pardon me, coming through!
I took it as Mark making fun of the bonesman.
