A few phrases I picked up from my mom:

"Ive got a great memory, but it's short." ;)

"That's my story and I'm stickin' to it!"

And one I came up with on my own (a variation of the first one):

"Oh, I've got a mind like a steel sieve."

I've also cribbed a few expressions from wonderful author Terry Pratchett, just because I thought they were funny as hell. My fellow Americans do look at me as though I'm, er, a few pickles short of a picnic, though:

"Arrrrgh! I'm too short for this shit!"

"Pull the other one, it's got bells on."
