Found it while perusing Babylon 5 on
IMDB.
Marcus Cole: [noticing Ivanova's not paying attention to his report] There's always the threat of an attack by say, a giant space dragon. The kind that eats the sun once every 30 days. It's a nuisance, but what can you expect from reptiles? Did I mention that my nose is on fire? And that I have
15 wild badgers living in my trousers?
[Ivanova glares at him]Marcus Cole: I'm sorry would you prefer
ferrets?
