I wasn't really sure where to share this, but I find it pretty amusing.
The neighbors have a smallish, very barky, very territorial dog named Tess. Any time we go out to work in our own back garden, there's Tess, lunging at the fence and barking her head off. Okay, mostly barking, not a lot of lunging.
What's so funny is that my cat Grumpy thinks that it's all a big game--he'll go outside when he knows Tess is out, sneak up to the fence and just INSTIGATE. Next thing we know, Tess is going nuts, barking and SERIOUSLY lunging at the fence, with Grumpy sitting on a landscape brick, cheerfully hissing (yes, it's possible), lunging at the fence and reaching his paw through gaps in the fence to try and claw Tess on the nose. Grumpy will actually LOOK for Tess every time he goes out. We don't have the heart to scold Grumpy because it's just soooo comically obnoxious.
