Yes, twice. When I was about ten one pulled me off my bike and bit me on the arm. Then about ten years ago my boss's guard dog (Rottweiller) bit me on the arm even though my boss was supposed to be holding him at the time. Luckily I was wearing a leather jacket so he didn't do much damage but I wasn't very impressed.
Cashback (e.g. Top Cashback) are when you go through that site each time before buying something online and you get cash back for everything you buy. Worth doing IMHO.
