Season 4: Episode 18 - Old King Clancy

Old King Clancy: Marshall and Barney decide to keep Ted in the dark after they discover that Goliath National Bank (GNB) is cancelling plans to build the new headquarters they hired Ted’s firm to design. In order to protect Ted’s feelings after such an intense year, they decide to let him ride out the two remaining months on the original architecture contract and set up an elaborate lie to keep him working on the design. Ted soon discovers the truth and Marshall and Barney scramble to get him some real work with GNB to save his job, but his plans are rejected and Ted gets fired from his firm. Meanwhile, the gang tries to pry information out of Robin after discovering that she’d once almost spent the night with a celebrity.
