"Led by Me" - Frankie Trowbridge and William Chase, "Get a room" Oh they did, this Episode.
"pose as a married couple" except when I did that the Irish girl that worked for the British Government, hated me more than "Frankie" of this Episode ever could, we were both working for the British Ministry of Intelligence (On paper I was working for U.S. Department of State UK, Brits needed an American).
There is also the other known "aspect" of this kind of "business", it is routine for the adversary's Counter Intelligence to have everybody under Surveillance, even if that means covert cameras in everybody's rooms, translation Frankie and William would have had to have had sex as recently married Mr. and Mrs. Trowbridge.
Everybody watching this is taking everything too seriously for a comedy comparing to Alias, saying Dumbest (which is actually a complement), Ridiculous (which is supposed to be), anybody that has done this kind of "work" before can see how much they are mocking, making fun, of this kind of "work".
