Night Court, Season 2

Harry:
Mr. Sleighbough, when did you first discover you had this talent to become invisible?

Sleighbough:
Well, it came on sort of gradually. See, at first, I was just boring. But then, I became inconspicuous.

Harry:
Oh.

Sleighbough:
Yeah, you know, like I'd be waiting in a doctor's office, or restaurant, or a barber shop, you know, whatever? And finally they'd say, "oh, I didn't see you there!" That's when it first began to take hold.

Harry:
And now?

Sleighbough:
I'm fully invisible! Yeah, I can be standing on the corner, yelling and waving my arms, cabbies are going right by and never even notice me!

Harry:
In New York City, imagine that.
