An American walks into his bedroom with share certs under his arm and says, "Honey, this is the big investment into pharamceuticals I've made..they're XIBO's : we're rich"
His girlfriend is lying in bed and replies:
" I think you'll find they're UK certs on XEN, you idiot"
The man say, " I think you'll find our money is safe..we can't ever sell them."
