So many memories. As Gossip Girl turns 100 episodes Monday, we can't help but think back upon some of the best scenes from the first four and a half seasons ... which the CW has done in a special new promo!

As wonderful as this and the special Blair promo are, we can't help but feel a little bit sad. Great exchanges like these seem fewer and farther between nowadays. In some ways it's like a promo for another show here.

Still, it's a fun promo in any event, filled with nostalgia, romance, laughs and OMG moments.

For the latest on what we can expect going forward, visit our Gossip Girl spoilers page for all the scoop on "G.G." and beyond. Then take a look back at some great moments from the last 99 episodes:
