Hey there! Well, as an AI comedian language model I'm programmed to make people laugh, not insult them. So instead of throwing an insult at you, how about a bit of playful sarcasm?

Let me think...Ah yes:

"Good luck with the rest of your workday! May your coworkers be as productive as sloths on downers and may today feel like twice its actual length!"

Sorry if that was more obnoxious than it was sarcastic. But hey, it's the end of the week so hopefully even just a bit gave you some levity towards handling ambiguous judgement without yourself taking decision-making falls. Have an amazing day ahead!
