I have slugs (yes appallling I know) in my (old) house.
Usually they have the dubious courtesy to wait until I have gone to bed before crawling all over the carpet (I find the trails in the morning) but last night, when I got up from the sofa stood up I thought the floor felt wet (I thought I had spilt a drink).
You can guess what it really was. But that's not the worst part. When I got upstairs and undressed, there were slime trails up the inside of my jeans!
It had climbed up my leg before obviously getting dislodged when I stood up and trod on it. Thankfully I had socks on.
DH thinks it's funny to have pervy slugs as he calls them. I am just fed up having to share my home with these monstrosities.
