Somewhat on Topic?

Oh man, today's Are They for Real Comment is great. It is a comment from my worm blog from a post titled, "Vacuum Bag in Bin". It is a post about whether or not it's a good idea to put the contents of your vacuum cleaner bag into your worm bin. I got this comment in response:

My site Blood circulation to and from with the penis retulages an penile erection. During sex-related arousal, any blood flow heightens to two mushy, structures (corpus cavemosum) this lie parallel towards the urethra, which often carries urine and also semen .

I got a kick out of them saying that what he's talking about happens during sex-related arousal. Is there another kind of arousal? LOL.

At first I thought this comment was just completely off topic. But then I got thinking...my vacuum cleaner sucks...and...well you get the picture.
