Behold! The face of someone who just learned that Grignard reactions don't work on all kinds of organic compounds! The meme references a chemistry joke about using organometallic reactions to "extend" something, but instead of getting the desired product, our amateur chemist got a shocking lesson in chemical incompatibility!
For the curious lab rats: Grignard reagents (that's the Mg and ether part) are used to form carbon-carbon bonds and can indeed "extend" molecules, but brominated compounds need specific conditions to work properly. Our friend here clearly skipped that chapter in Organic Chemistry 101!
