Once I had to reapply for my old job, When the interviewer asked for my skillset, I listed all I could do. When he interrupted and said "Tell me, is there anything you can't do?" I said "Yes, impress you."
A month later they (re)hired me as no one was trained to do my role. I spent 10 minutes each day standing at the photocopier next to his desk copying any old tat, because my grinning face and the noise of the rattling photocopier visibly irritated him.
When he was sacked, I made a special trip of offering my condolences, while photocopying an extra big bundle.
I try to be nice, honest.
