Science is a Verb, Science is a Doing Word
Is there anything better than the combination of than cats, science, and jetpacks? With the possible exception of maybe Liz Lemon and bacon and robots, no. This tee, like most sold by the webcomic "Questionable Content," doesn't seem to refer to anything that happens the strip, but who cares? Not everything on a webcomic tee needs to be an out-of-context reference to a punchline, especially if there's already a magical jetpack cat flying through the stars on a voyage of scientific discovery.
Also, it glows in the dark.
