You can't celebrate if you don't score; perhaps Arsenal and Crystal Palace are onto something.
In a week where footballers have been pilloried for breaching Covid protocols by continuing to embrace when celebrating goals, these two teams found an effective way of avoided any controversy.
Here's hoping it doesn't catch on. In fairness, as goalless draws go this was relatively entertaining - and by the end neither Mikel Arteta or Roy Hodgson would have been too disappointed with a point. Though, Palace striker Christian Benteke - who missed a series of glorious chances - may feel differently.
