James does not has a memory

James:
I knows stuff.
I have a brain full of stuff.
It's so full of stuff that stuff is constantly trickling out of it.

Mystery:
yeah...
like a sieve ;P

James:
Something like that.
Just remember that the unimportant water is allowed to trickle away
while the important spaghetti is kept.
"Spaghetti" in this case representing Doctor Who trivia and Beatles lyrics.
....and water being my friends' birthdays.
