When you're done taking a dump and you stand and turn around to admire your mudbaby. Dismay is a common reaction, as some may spot peanuts, corn, or other bits of partially digested foods, yet they are certain that they hadn't eaten such things recently.
Tommy's kinda upset today. This morning, as he engaged in a Proud Papa Glance, he saw that it was riddled with peanuts, but he's allergic and can't eat peanuts! Leads him to believe he's not the real father of that turd.
