They just keep upping the ante on these Couch Gags, don't they?
I'm generally not crazy of using recycled plots (sounds too much like Bart raising bird eggs that turn out to be lizards), but Bart's antics with the pigeon were hilarious. Unfortunately, it intersected with the recycling of every "Dump Santa's Little Helper" plot, which I couldn't care for too much. I do, however, love watching Bart do the strangling this time around.
