Here’s a call to worship suitable for Holy Humor Sunday (aka Bright Sunday or Laughter Sunday). It comes from the Trinity United Church website. It could be done responsively or with one voice.
Call to Worship for Holy Humor Sunday
Joy is loose,
In the wiggles of the children,
The whispers of the youth,
The smiles of the adults.
We praise God for this glorious day,
Let the praise break forth
in the most unlikely places and in silly ways.
Joy and praise fills our hearts and in our songs
Let the laughter be deep,
for we are God's people.
