You can find hundreds of videos featuring attacking animals. In fact, one of the last viral 'animals attack' videos involved a man walking through a park and a goose. I don't think I have ever heard of a sheep attacking someone, yet, that is exactky what happens in the below video. Although, I don't think the sheep was 'attacking' as much as he just saw an opprtunity to mess with the guy. The guy is just fishing on the bank of a lake, minding his own business without of course, seeing the sheep behind him. Can't you almost hear the sheep saying, 'are you kidding me...this is almost too easy'? Anyway, the sheep hilariously rams the guy into the lake. I'm telling you, I can just hear that sheep saying...."What a tool"! See for yourself.
