Note to self, don't mess with magicians.
You and Basil were watching a magic show, and the magician calls Basil onto stage.
Basil: Sure, I'll play. You probably just gonna "pull" something out of my ear.
The magician didn't take that too kindly, so she pulled out his intelligence. As he drools all over his paw, the magician pulls out a handkerchief over him and, PRESTO! Basil has regressed again! But the magician isn't done yet.
Magician: Now, why don't we let the bunny try the next trick! Can you make the night stars disappear?
Basil: Stahrs? Dis-ah-peer?
He thinks, then he saw that there's stars on his diaper, and he now understood the trick and bends his knees.
Basil: I knoh! I knoh how ta make stars go away!
His tail has flagged, and without warning, he starts wetting his diaper, causing the stars on his diaper to disappear and to droop to his knees, causing some watchers to chuckle and coo.
Basil: See!? Stars ahh gone!!
He proudly shows off his droopy diaper, before you came up and scoop him up. As you carry him to the nearest changing station, he finally snaps back into reality and realized that not only did he regressed, but also embarrassed himself in front of many.
Unsurprisingly, he blushes hard. His hands all over his face as he refused to meet you in the eyes...
