Little Bun had too much caffeine at his Auntie's wedding. Any caffeine is too much caffeine. Caffeine for Little Bun is prohibited.
We discovered that he had had this one Pepsi too many when his eyes flashed rapidly, he giggled maniacally, and tried to breakdance in his rented tuxedo.
Later in the evening, after he'd settled, he had this to say:

"I'm really sorry that I disobeyed you and my disobedience led to misbehavior. I asked the lady for an Orange Soda but I guess she only heard 'soda' so she gave me a Pepsi and once I had that Pepsi . . I'd never HAD a Pepsi, and I couldn't pass up my chance. Now I'm sorry I took that chance."
