Gosh, don't forget the old:
Although I've plenty to prove bigfoot exists, I chose not to share with modern science because bla, bla, bla.
Although I could easily lure the creatures into camera traps, I choose not to do so because bla, bla, bla.
You don't have the correct mental aspect of it all, as the creatures know if you've been naughty or nice. Christmas is a trip with them, eh?
You can never know the beautiful feelings of knowing bigfoot, because you're just not hip. I know more, but you will never know what I know.
Bla, bla, bla.
Oh, and the really angry MIB is kinda funny. Hello, MIB. How ya doin'? Are you OK?
