Deaf Trial

Listen up, buttercup. This joke is playing on the double meaning of the word "hearing." You see, a "hearing" can mean the ability to hear, or it can mean a legal trial or inquiry. So, if a deaf person is on trial, they can't literally "hear" the trial, making it a play on words. It's like when you try to understand advanced math, you're technically "hearing" the explanation, but it ain't registering, is it?
