Here's the situation, a friend (in a position of authority) called and said, someone who wished to remain anonymous wants to give me and my wife an expensive gift.

I've been struggling with a "Thank You".
If anonymous knows us that well I have been thinking a little humor to start would be OK.

"Was it something I said or did ..."
"If I don't shoot the messenger, do I hug and kiss...."
"Do you realize what a burden you've placed on us..... now we have to be extra nice to ALL our friends"

Well, I think you get the idea.

What are your thoughts?

I will appreciate any and all suggestions for special phrases (sincere or humorous ) that are appropriate.

I'll close with just a plain THANK YOU!
