This is the hilarious moment a pack of hungry giraffes assail a teenager on his first ever trip to the zoo.

Carson Miller decided for her two-month anniversary date she would surprise her boyfriend Hunter with a trip to the zoo for the first time.

In the clip, filmed on March 12 in Texas, Hunter screams in the car as he feeds the giraffes.

Their long tongues can be seen probing around inside the vehicle.

“Even after the screams, we had the best time ever," Carson wrote later online.

This was me and my boyfriend’s 2 month anniversary date idea. He’s never been to a zoo so i thought i’d surprise him. we had the best time ever. when we asked each other at what moment did we realize we were in love with each other, we both replied “at the zoo”.
