I would never barf in your urn!
Saying you’d never do something, then doing it so bad it makes your enemies cry.
I’d never steal your lunch money, then I took it and ate it in front of you.
I’d never talk to your dog, then I insulted it and it barked at me like I owe it money.
I’d never barf in your urn, then I did it and it looked like a science experiment gone wrong.
