Funny Good Sir I Believe I have Shat in My Pantaloons Baby Onesie Saying

Updated December 3, 2025 by Jan of Unique Baby Gear Ideas

The second on our list is a baby onesie saying "Good Sir, I believe I have shat in my pantaloons".  However rare it may be that it would be necessary for our little ones to inform us; it's still so funny. 

The thought of an infant actually being able to verbally notify us that his diaper is in need of a change makes me chuckle.


Can you imagine the laughter and looks of amazement if somehow we could make it look as if a baby was relaying this message?
