I envision Jason Lee on stage yelling to the crowd “You get a prize and you get a prize and you get a prize.”
How about some surprise prizes - to be brought by the representing church or the person nominating. These could be both “Thank you for a great job” prizes that would be serious and “Really you did that prizes” that would be goofy (not insulting) prizes. Both would be given on stage and the people would have to open the box in front of the crowd.
