We're all familiar with the story where a male actor tries to play a woman. For me (and this has absolutely nothing to do with this caption), the best in this sub-genre remains a movie named Stage Beauty . It's set in the 17th century, and its plot revolves around two people (played by Claire Danes and Billy Crudup) during a time when gender roles were changing in theater. I won't completely give away the plot (if you want a summary, click on the link), but I will say that you should give it a shot if you get a chance.
As for this caption, it's just a silly bit of fluff in which a sissy doesn't quite realize who and what he is.
