DJ Grandmaster Flash has been giving birthday, back-to-school, and holiday wishes to grandchildren all over the web — without even knowing it. That's because grandparents have been hilariously baffled by Facebook's auto-fill tag feature, one that apparently switches "Grandma" to the hip-hop artist's page name with just one click. Unsurprisingly, the Internet got wind of the funny phenomenon and has been keep tracking of the best grandma fails on a Tumblr page [1]. Grandmaster Flash himself weighed in:

"It's true I get a lot of posts from Grandmas. Hilarious now I know why — Respect Grandma and Grandpa. P.S. This is Hip Hop!"

We've rounded up a few of our favorite fails here.

Grandmaster Flash wants you to make good choices.

He's got your neck pillow.

What is this Grandmaster business?!

So much love.

Best birthday wishes from Flash, Anthony!

He's a hugger.
