Male Tomato??

Had to take a picture of this weird tomato.  I'm not much of a vegetable gardener... perhaps this sort of thing is common?  Anyway, this came from our back yard garden, and now it's got me worried.  Hybrid varieties and genetic engineering gone a muck?  Environmental toxins causing chromosomal mutations?? 

Who's to know what's next...  Killer tomatoes??!

OK, so perhaps I'm overreacting.  At any rate, enjoy your weekend, but watch out for those tomatoes!
