Last party I was at, some guy with a concave chest lay down on the ground, and we all took turns drinking cheap red wine from the hollow. All 20-30 of us. We were all very, very, very drunk. 
This Saturday is my friend's 18th party, and we're considering hiring a male stripper to randomly turn up at some point during the night. No idea when, all my friend'll hear is a ring on the doorbell, and on the doorstep will be a semi-naked man wearing a naval officer's uniform who's all too eager to show his "new recruit" the ropes.
