Rusty goes in for his annual check-up & it turns out his new doctor, Cedric Van Smidtickle, is a tickle beaver!
Doctor Smidtickle is testing Rusty's reflexes. Rusty is trying to endure for the sake of the test, but it it goes on so long that it causes his toes to curl, spine to tingle, as he burst into giggles and just wants the test over with! HA! HA!
