Also a character in a 'Jeeves and Wooster' (P. G. Wodehouse) episode who was a huge bully of a man riding roughshod over Bertie Wooster's life. Spode however, had a secret; Jeeves found out from his connections at the local manservant's club that Spode designed and sold brassieres. One whisper of the 'brand' and Bertie was out of the woods, so to speak.

The jaws that bite, the claws that catch!

"My sister's boyfriend is a real spode; he just sits around eating Doritos and slowly becoming part of her couch."
