The Relevancy of Animated GIFS in the age of YouTube

The entire 15 second clip as a 3G2 Video clip is only 188kb, as an animated GIF, this small part of it is over 600kb. So the question remains why? why did kirk’s fall look so fake? who was he trying to impress? why spend the time to make this an animated GIF? and why did al roker deflect to the weather channel?
