Things That Make You Go "EWWWWWWWW"

Went outside this evening and observed two slugs on my house, about 3' off the ground, and they seemed to be in some form of a race.  I haven't ever seen slugs moving this fast.  When I came back past them a few minutes later they were at 4' and were.....um.....having slug sex.   

I couldn't resist taking pictures of the lovely couple.  The slightly out-of-focus picture is a closeup of their apparent sex organs.  In the other picture you can see how intertwined they were.  
And for those of you that think I need to put pictures on my blog...this one's for you! :O
