Things kick off with some overly excited Sesame Street characters waiting for 1D to show up and they're every bit as fangirly as in real life. When Harry, Zayn, Liam, Niall and Louis show up on the scene, the girls are impressed enough that they're there but are waiting for "1D." Literally.
The number one and the letter D show up and the One Direction guys join in on the fangirl mania. We can't keep our eyes off of Harry's screaming reaction and all the guys getting in on hugging 1D. This gif says it all.
