The day the worst guac in history was forged. It made me want to jump off a 20 story building. It looked like the fake Krabby Patty from Spongebob. It look cement mix and dry wall. I do not know how any person could make that and think they did a good job. I bet homie ate that and said "I think I have a shot of being a pro cook!", nah homie, you finna be a pro cement maker!
Yo, Today is Guac Day. Time to remind ourselves of that atrocity!
