Freshly dropped in my mainbox via PrismBrony, hot off the video press.
And a movie trailer parody, remember the movie Kick-Ass? Now with ponies. From the Bronycomm guys.
And last one by MrYaridovich, owner of the original Pony Synchtube, parody of Beavis’ trip scene from Beavis and Butthead Do America.
