A Reddit user got the surprise of her life when she found out her Secret Santa was Bill Gates.

The 24-year-old identified only as Rachel got a 7-pound package in the mail as part of the site's annual online gift exchange.

Besides a cuddly cow and a travel book, Gates donated a cow, via Heifer International, to a family in the developing world in her name.

He even included a photo to prove it was him.

Rachel's post, in part, read:

"Thank you so much Bill for a fantastic and thoughtful gift. I'd really love to send a thank you card to you, but if not, I hope this post and message suffices. Thank you so much!!!!!! I will think of you every time I read my book, which will find a nice home on my coffee table once I'm done reading it. 10/10, I would receive a gift from Bill Gates again."

"Sorry for the apple ipad on my wishlist, that was really awkward," she added as a postscript.
