Whether you find it funny or not, Harambe has become the internet’s meme of the summer.

It started as a response by what many people believed was an overreaction to the tragic death of Harambe, a gorilla in the Cincinnati Zoo that was shot after a child fell into his pen. The meme has since grown to such an extent that the Cincinnati Zoo has been forced off Twitter and fans commonly shout Harambe’s name at sporting events.

And now, a professional golfer is joining in.

Smylie Kaufman introduced himself to many golf fans with some good play and an even better interview with Jim Nantz at this year’s Masters. Now he’s honoring Harambe with an “RIP Harambe” stamp on his sand wedge.
