    My sound was low on this video, so I couldn't hear it to well and I swear to god I heard "dick" everytime he said "tick" in the intro. I don't know if this means I need to stop thinking about cocks or if it means I just have bad hearing, or both. But I got so fucking confused.

    It's commonly reported, but I don't think the time attached before being able to transmit Lyme is correct. I know this is anecdotal, but I contracted Lyme from a tick that was attached for no more than approximately six hours, and boy howdy does that suck. It's ok now though, thanks to our good ol' friend Doxycycline.
