This is another A&J from 10 years ago. I try never to discourage discussion, here or on the GoComics website, but “No.” Arlo would not really do this. He’s a cartoon character! His job is to do dumb stuff that we can almost imagine ourselves doing. As for all those keys that accumulate—and that is no exaggeration—my best solution is to put them on a big ring and give them to small children. They love to play with key rings! Just make sure none of the keys actually fit any of your doors.
