MATH PUZZLE: Can you replace...

A little boy was in a relative's wedding. As he was coming down the aisle he would take two steps, stop and turn to the crowd (alternating between bride's side and groom's side). While facing the crowd, he would put his hands up like claws and roar. So it went, step, step, "ROAR," step, step, "ROAR," all the way down the aisle. As you can imagine, the crowd was near tears from laughing so hard by the time he reached the pulpit.

The little boy, however, was getting more and more distressed from all the laughing, and was also near tears by the time he reached the pulpit. When asked what he was doing, the child sniffed and said, "I was being the Ring Bear."
