“Coffee! If you’re not shaking, you need another cup”

“Coffee! If you’re not shaking, you need another cup” is a jocular coffee saying that has been printed on many images. “COFFEE! if your not shaking….you need another cup!” was posted on Twitter by Casey Todd on October 7, 2009. The saying probably comes from an image.

A second sign reads, “Coffee! If you’re not shaking, you need another cup.” Who am I to disagree? Time for cup No. 2.
