Who is paying the taxes on that? The person giving it probably didn't/hasn't paid the gift taxes. This sort of irregularity is going to get you audited or a closer look and that isn't going to be be fun. Where did that money come from? Oh, it came from Tornado... now you're going to get audited to make sure that this isn't you sending yourself money. That's really not going to be fun.
If you got money, its going to be taxed somehow. Trying to avoid paying taxes on that money is going to get you into more trouble. Any investigation on the history of that money is going to cause problems for the person.
