Ten
1. Cutting an apple with a butter knife, not as easy as it looks. On the bright side, when you stab yourself it doesn't hurt.
2. Trying to stand while riding a broom may sound like a good idea after a few things of firewhiskey, is not actually a good idea.
3. At a bar, if a guy asks if you want to see his broom, just say no...unless he's very cute or actually holding a broom.
4. While riding a unicycle looks easy, it really isn't and it is more likely that trying it will lead to a face plant.
5. Playing Quidditch inside the house may seem like a fun idea, but if mother comes home, the fun is replaced with yelling. Lots of yelling. Even if it was dad's idea and he's the only one that actually broke anything.
