The word of the day is: PHOTOBOMB! "It's when someone takes a picture, and then we jump up in the background and surprise them, and then they don't know that we're there until they see it on their phones!"

It has been a pretty depressing week in the news. Every time I opened up any social media feed I was bombarded with more celebrity death. So I thought what we all needed was a nice adorable palate cleanser at the end of the week.

And what better way to cheer people up than by having them watch Jimmy Fallon teach Elmo, Cookie Monster, Big Bird, and the rest of Sesame Street what a "photobomb" is??
