Ah of course, this topic is about avatars and signatures. The avatar is, of course, Susan with the Death of Rats as, I'm sure everyone knew.
The signature? As you might have noticed, I have been away for a while due to personal circumstances relating to a car accident so I'm not sure why I chose this specific quote. Probably because there are so many incredibly good ones, I could not make a choice and picked this one because it's said by Ridcully and hey, 'why not?'.
