Unintentional Self-Consciousness

My Boss gave me a mug for my birthday. The writing says

"All men are animals. But some make better pets"

I was chuckled when I read it. I couldn't help but thinking if he was beginning to be self-conscious for whatever reason. And that he was speaking on behalf of his 'kind'. Until he asked "Kok ketawa sih, lucu ya, emang artinya apa?"

Gubraak...!!!!
