Penpal letter
When Reba arrived with mail for Pee-wee, it would usually be letters from his international pen pals. Pee-wee would then sit down on Chairry and read them. He started with the country or state (China, New York, Australia, etc.), followed by Globey pointing them out on his head. On one particular occasion, however, Pee-wee received no pen pal letters at all (because he didn't write any letters himself), which caused him to go into an infantile tantrum. One of the few complaints of the show (other than the Secret Word screaming) was that the people portrayed in the pen pal letters were often very stereotypical of their native country or state.

This segment actually originated on The Pee-wee Herman Show.
