Let's see, my sister's husband built their house by himself, well he had help, but not from any architect or construction companies. Just his college friends. So, it can be done so that's not the lie. It's probably easy to drive on six continents as well, but have you had the time to do that? hmmm. I also believe the third one so this one is actually kind of difficult really.
I'm going with number 3 as the lie it's the only one that isn't really that huge of a task making it the over-looked one to throw people off.
