Quote from Barney in The Sexless Innkeeper
Barney: Look! I'm sorry that we have been dodging your calls, but we respect you guys too much as friends to give you some song and dance. You deserve the truth. [sighs] The US Navy has found intelligent alien life at the bottom of the ocean. For reasons I can't explain, Robin and I have been tapped to lead the expedition. Lily: Wow, Barney. That kind of sounds like the stuff you say to girls when you're too much of a coward to dump them. Marshall: Yeah. You know, that's exactly what it sounds like. But if that's true, that's awesome.
