“Barney : Let’s see, what club should we hit first ? There’s club “Was”, there’s “Wrong”…
Marshall : Those places shut down a long time ago.
Barney : Oh no!
Marshall : Yeah “Oh No” shut down too!
Ted : There’s “Where”.
Jerry : Where’s “Where”?
Lily : “Where”’s where “Was” was isn’t it?
Barney : No “Was” wasn’t where “Where” was, “Was” was where “Wrong” was right?
Jerry : Okay…
Ted : No “Okay” that place is lame.
Robin : “Okay” is lame ? I thought “Lame” was a gay bar… Or is that “Wrong”
Marshall : That’s wrong, that’s not “Wrong”.
Barney : Guys, focus!
Robin : Oh I like “Focus” let’s go there!
Ted : Where?
Robin : Not “Where”, “Focus !
Lily : I thought “Focus” was closed?
Barney : No, “Was” was closed, once “Was” shut down it reopened “Is Closed”
Marshall : “Closed” is opened!
Robin : No, “Closed” is closed.”
