My dad, cousins and uncle worked there - my cousin just by liverpool street. I didn't try to think of any jokes, but somehow I got a sort of
<Tony Blair> Someone set us up the bomb!
<al Qaeda> All your base belong to us!
thing in my head.

Edit: I didn't say it was meant to be funny
. It's because I was explaining the joke to someone who wasn't a heavy internet user in the last week.
