I don't have hands
A rude way to say you're too lazy to help someone else.
My friend asked me to help her with her math. I said, 'I don't have hands.' She said, 'Then use your brain.'
My dad told me to clean my room. I said, 'I don't have hands.' He said, 'Then use your face.'
My teacher asked me to write the test. I said, 'I don't have hands.' She said, 'Then use your brain.'
