Yet another glitch I found. I suggest doing this in Firing Range, because it really won't help you in a real match.
1. Place a Sentry.
2. Stand inside your Sentry and use a Sheep.
3. Laugh.

Mind explaining it to us who don't have W:OW2?
Also, because it could be a version thing: do you have the DS version or the PSP version?

PSP let me explain better. Place a Sentry, stand inside it, use the Sheep. The Sheep will be stuck.

Theres another glitch aswell, Sheep and Oil drum. Use the sheep, let it go near a oil drum, (on a hill with it on the highest bit), and the sheep will be Unable to jump over.

I wouldn't really consider that a glitch, because the sheep can only jump so high.
