It's Time for a Gif Party! And All Your Gifs Are Invited

It's Friday and that means that you — and all of your gifs that have been waiting so patiently throughout the week — are invited to a gif party. Why? Because you guys are awesome.

So send in your favorite gifs and let's gif this party started! (Note: Gifs are encouraged but gif-puns will be accepted in lieu of gifs.)

H/T to commenter dpeif for this week's Carl Sagan gif, submitted via last week's inaugural Friday Gif Party.
