Like any good protest, rally, and march in the tumultuous, volatile year that has been 2017 thus far, the March for Science was chock full of people with handmade signs with clever clapbacks in defense of science. And despite pouring rain that threatened to make these elaborate magic marker masterpieces run, science supporters of all kinds came out in full force with signs that proudly rocked double entendres, political “oh no she didn’t!”s, and earnest appeals to protect science and therefore, humanity.
