Since honey crashed so will I.
Do you have anything "fun" at the beginning of meetings, like a sunshine jar where people put in little notes to each other? If you get some of the "energy" out at the beginning of the meeting - ESPECIALLY if they're on Sunday and everyone is still buzzing about the weekend - it makes the actual "formal' part of the meeting go more smoothly.
Something else maybe fun to do is instead of saying "here" or "present" when the role is called, say your favorite makeup brand or pizza topping or something silly like that.
Obviously if this goes against your formal meeting rules somehow, don't do it.
