After getting in the White House, D.Trump gets a letter.... ... from the Iranian president. He opens it and to his surprise there is a paper with a weird looking code on it:
370HSSV 0773H
All confused, Trump contacts the FBI and forwards the letter to them in hope they can figure out the meaning, but they weren't able to. Trump gets angry and sends the letter to both the CIA and NSA, and they also fail to figure out the meaning of the letter.
One of the agents suggest Trump to ask for MI6's help, so he does and few minutes after a British agent sends a fax to his secretary: Tell your president he was holding the letter upside down.
