Party theme - BREASTS

I live in a co-op with 15 other people. we are having a party next weekend and each room has to have its own theme and drink to match. Since the girl who lived in the room before me had a vagina theme, I thought I'd keep it related and would like to have the theme of Breasts, especially since one of my favorite drinks is the Slippery Nipple (bailey's + butterscotch snaps). 
My question is: 
Do any of you have ideas for room decorations or related actitivities?
And 
Can anyone think of boob-related songs?
