Flat-top.
I got back last night at about three, and knocked on my neighbour's door, got her up (despite cries of "I'm sleeping"), jumped into her bed and fell asleep. She woke me up when she got sick of not getting any sleep because I kept on elbowing her and stuff, and said "Look - I haven't had any sleep and I have to be up in" - looks at watch - "oh my gawd - FIFTEEN MINUTES".
I was still so drunk that I just laughed at her. And I was still dressed in drag from my fancy dress last night.
