doesn't that hurt their beaks?

So my gay and I were walking around downtown the other day and happened across Ivar's on the waterfront. We went inside to get away from the cold, even though all we really wanted was fish and chips. Upon getting inside, we realized we could get the same exact fish and chips for about 10 dollars cheaper from the outside vendor. He ordered prawns and chips and I got new cajun style fish and chips - wicked good!! Anyfish, we head over to the enclosed seating area that's made of plexi-glass windows and filled with plenty of heaters. We sit down and immediately notice there are about 5 pigeons roaming around, stuck inside. But things didn't get really exciting until the pigeons starting flying full speed into the windows and promptly falling down with that calm head bob as if nothing happened. I almost died laughing when I figured out what had happened. We even tried throwing fries at them to lure them towards the door to let them out, but they wouldn't even follow us - they just kept flying themselved directly into the glass. All I could think about was The Bee Movie's classic line, "Maybe this time...Maybe this time...Maybe this time..." Fuckin stupid birds...
