If you’re like us and have been on Twitter, the first thing your eyes would have noticed right away was that today is “National Cleavage Day.” Historically speaking, today yet is another example of a “corporate holiday” – it was originally started by Wonderbra. Unlike Valentine’s Day and Hallmark cards, you won’t hear a single straight man complain about this fine example of product placement. For 364 days of the year, men are constantly fighting the urge to get caught staring at a woman’s cleavage.

Today, however, it would seem that some of the better-endowed ladies have taken it upon themselves to do all the hard work for us. There are more boobs on Twitter than ever, and that’s really saying a lot. Feel free to check out the Twitpics elsewhere, but we’ve pulled some of the best real photos of massive mammaries below.
