The G and I opted not to subject our cousin’s children to a popularity contest/BCS-like ranking system and consequently did not have a flower girl or ring bearer. But if I were to do it again I would look into having a ring bear.
I would train it to walk that goofy, upright bear walk down the aisle, carrying a little silk pillow with the rings on it. After it gave them to the minister, he (I assume it would be a he-bear) could back to four paws and sit their quietly during the ceremony. But if he caused trouble, I think one of the groomsmen could have a beehive on a long stick to distract him. Probably the G’s brother because he’s tall and has long arms.
At the end, immediately after the “…introducing for the first time Mr. and Mrs. Pygmalion…” he would stand up again and growl his bearish approval like the last scene of A New Hope.
Oh, by the way, I lost my wedding ring recently. It was an ill-advised course of action and, as you counsel, I strongly recommend against it.
