I am a former house page and this is a conversation that has gone on more then once over the phone:
Page: [Party] Page desk how may I help you?
Intern: Hi this is [X] from Congressman [X]'s office and I need something picked up at [XXXX]
Page: And where will it be delivered to?
Intern: Well, it says Bill Hopper on it, do you know who Mr. Hopper is?
Page: Yes we know exactly who Bill is, we'll be right over. (while trying not to laugh)
They thought that the bill hopper was a person...genius.
