Let's hear it for brain farts!
One day, Seras was bored. She fell to wondering about strange things…
Later:
"Master?"
"What?"
"Could I ask you something?"
"Very well. Make it quick. I'm busy."
"Master, how old are you?"
"Why do you ask, police girl?"
"Oh nothing, just curiosity."
"…"
"Master, are you all right?"
"…"
"Well…?"
"Umm…cheesecake?"
"Master!"
"Pie! Tart! Cake?"
"Gah! Fine then! I'll ask Walter."
A few minutes later…
"Walter, how old is my master?"
"I'm not exactly sure, Seras. He never deigned to tell me. I would guess a couple hundred years though."
"Hmm…Walter?"
"Yes?"
"How old are you?"
"…"
"Walter…"
"Um…cookies?"
"ARGH! What is with people today and various assorted pastries?!"
Run away. Very quickly.
