XKCD Isn't Funny - #1710 - Walking Into Things & #1711 - Snapchat
This one works. I wish the neat landscape didn't go away after the first panel, though. There's a real missed opportunity to have a rock or something in front of him in the last panel, and he could be turning his head to say his part of the punchline, so it could be a little bonus joke that wouldn't be instantly noticed and therefore adds rewatch value.
Also, really really minor quibble, but isn't it technically not a control group, just a control, since it's just the one guy?
The joke is that snapchat photos are deleted by the service quickly, but it should still be viewable if the prize was "just" awarded. If the implication is that Bald tapped the snap but didn't see it, then Randy's making jokes about stuff he knows jack about, because you get one replay and can pay for more.
The real question is how the hell did snapchat win a Pulitzer? I looked it up and that's a journalism thing! You can't journalism in ten second videos!
