[on film:]
Cliff: Hi, Mr. and Mrs. Boyd. I'm... Hi, Mr. and Mrs. Boyd. I'm Cliff Clavin, a good pal of Woody's and a proud member of the U.S. Postal Service. Come on along with me and I'll show you the kind of work we do routinely at the USPS. Morning, Woody.
Woody: Hi, Mr. Clavin.
Cliff: Hi, Judy! [she is silent] Well, let's see what we got in the mail bag. Well, look at this! It's a letter all the way from Guam to a man right here in Boston. Wow! It's made it this far, and it's up to me to see that it gets where it's intended. [Woody walks on the home owner's lawn] Woody, I could get in big trouble for that.
Woody: Oh.
Cliff: I'm only one link in this chain. A strong link, a vital link...
Carla: [in real life] A missing link.
