George Lichtenstein, better known as Lichty, created the comic strip Grin and Bear It in 1932, and he worked on it until his retirement in 1974. It was picked up by Ralph Dunagin and Lichty's assistant Rick Yager, and later Fred Wagner, and ran all the way up to 2015. Quite an impressive run for a single panel gag strip.
This strip in particular highlights one of the perils of children's plays, especially Christmas plays. Children are already excitable, nervous, and probably shy when it comes to performing, and their normal response seems to involve just ignoring what's going on and making their own fun out of it (at least that's what I remember doing when I was that age). Adding in the excitement of the Christmas season probably doesn't help matters either. In this case, I think probably making only one of them the angel and having the rest of them be shepherds or something might have been a better idea. That way they would at least have some fake sheep to play with.
