Creepy crawlers blasted onto Conan last Friday — did you catch the episode? If you were loving that gigantic cockroach and feel the need to spy more reptiles and insects, check out the animals presented on this late-night show. Clearly Conan wasn't as into getting a close-up as the expert, Nigel Marven, but I loved seeing the animals (especially "Percival") — with appearances from a Goliath spider with a 10-inch leg span, a rare double-headed snake, and the largest python in captivity (365 pounds!), see the creatures . . . with only minimal blood lost in the process.
