There are many scientific polls and studies determining which female body parts are favored by men. The typical result ranks eyes, lips, and boobs etc. at the top of the list. Besides the obvious muscles (arms/back/shoulder) and facial features (eyes, hair) I think what's sexiest is a man's sense of humor.I've always said if you can make a girl laugh, you can make her do anything. Humor shows a great deal of confidence, reflects a strong sense of self and an awareness of one's environment. If a man has enough wit to engage others in conversation, it will captivate the hearts of many. Plus, never underestimate the medicinal powers of a good 'ole belly laugh. Humor can help break down walls and open doors to greater possibilities in a relationship. For all the girls lucky enough to snag a guy with comedic timing like Fred Armisen or can nail an impressions like Steve Carell, just know he's a keeper.
