WEDNESDAY 9 P.M. USFL Football, ESPN Classic. San Antonio Gunslingers at Houston Gamblers. At one hour, this is a 7-inch edit, if you will, of pretty good game. Houston, lead by Jim Kelly, got a quite a surprise from the lowly Gunslingers. Can you believe this game was played 20 years ago?
THURSDAY 10 P.M. Human Cannonballs, Discovery Channel.

After enjoying some of the hidden wonders of L.A., they'll reach the end of their trip as the sun sets at the Santa Monica pier. California, here we come ...
SUNDAY 8 P.M. Wild, Wild, Web, Animal Planet. And you thought the World Wide Web was something. For some insect species, silk is a formidable medium of information that encourages social interaction.
