This one here was used by M to bludgeon his brother who as he put it, "messed up my train tracks."
See the band aid on his forehead? Its hiding a deep gash caused by his brother (See #1)
2. Toys with no "off" switch. I mean come on. You really need to think this one through. Yes, I'm sure it seemed cute in the store. You poked it, pulled it, picked it up and it made some automatic sound that you thought would be entertaining, (and for a little while, it was), but at half passed midnight, when all the toys are put away and the house is silent, the last thing you want, is to here toys talking and laughing as you walk by them. Trust me, you will be afraid, very afraid. I know you've seen Chucky.I guess the sounds are motion sensitive, not cool.
3. Pieces. Lots of pieces. I have to confess, I am guilty of this one myself. Two words - Lego duplo. Yes, it was me. I bought the Lego duplo for Christmas, and it has now taken over. Don't get me wrong, I actually love Legos. I think they're a great creativity stimulating toy, but the problem is - kids don't pick up their toys (see #1). This really wouldn't be a problem (technically) if the mess was in the kiddos' room, however, we all know that toys are migratory, so you're bound to step on a lego say … hopping out of bed?See the open door? That's my bedroom. Now isn't the Lego placement just a tiny bit suspicious?
Now this is my short list. I'm sure you have some more I didn't think of, so what's on your list.
