Batman meets Robin

I was munching away happily yesterday at lunch - completely absorbed in All My Children - when I heard it. Thunk. Like any good homeowner I figured it was either one of those sounds a house makes intermittently or it was a burglar. And like any good homeowner I sat in my chair and thought "It'll go away." Thunk. Thunk. Thunk. FINE. I will go see what is going on. So I went down to the basement (during a commercial break of course). It seemed to be coming from the window. I opened the blinds and thunk thunk there he was. For some reason this poor Robin is convinced of one of two things: 1) our window is the wrong place and he should be able to fly through it to who knows where or 2) the nasty Robin in the reflection will NOT leave him alone. I was not sure what to do. Because I am so intelligent I figured banging on the glass when he "attacked" would be a good plan. It scared him away for 5 minutes. Just long enough for me to walk back upstairs, plant myself in my chair, and turn my attention to my show. Thunk. "Forget it. Be stupid if you want. Knock yourself out. I don't care!" I yelled down the stairs. Several minutes and thunks later I go back to work.

Fastforward to 6:00 p.m. Brian arrives home from work and we eat supper. We are in the middle of "American Inventor" when thunk.
J: Did I happen to mention to you that there is a Robin that habitually flies into the window downstairs?
B: No.
J: Well, there is a Robin that habitually -
B: When?
J: This noon. But he's back. He's probably been doing it all day.
B: Great.
Brian gets up and walks downstairs and watches Robin beat his wings against the window.
B: I'm just going to go throw some softballs at it.
J: You think you can hit a flying bird with a softball?
B: looking dubious
J: Why not just get your tennis racket?
B: What? And kill it?
J: Hitting it with a softball wouldn't kill it???
B: Oh.
J: I don't care.
Brian went outside and I am assuming he attempted to frighten the stupid creature away. I did not watch but I had lovely images of him swinging madly at this foolish Robin.

So the moral of the story is...ummm... any ideas?
