Sometimes, you can get away with being lazy just by being funny.
Boss came into my office looking all flustered. He looked at me with a face full of tension and said, "Meng, I need you to give me a hand". I said, "Sure". Then I stared blankly at him and clapped for a few seconds. He laughed and left my office. I didn't even have to do any extra work.
Daughter wanted to race me up the stairs. I didn't want to. She got in a "ready" position and asked, "Race?". I said, "Chinese". I didn't have to run.
