From "I Love Lucy: The Marriage License (#1.26)"
[finally admitting the joke he played on Lucy when she thought their marriage license might be invalid
] Let me explain the whole thing to you, will you please? The whole thing is a gag, honey. Now, I'll tell you what happened. Look, heh, heh, heh, you know, Fred Mertz had a friend, he had a friend down at the license bureau, see, so I asked him to tell his friend to tell you when you got down there that the license was no good, and that we were not married at all, heh, heh, that's what I told him, and he did it, you know, heh, heh, heh. Isn't that funny? Heh, heh, heh.
