I always touch base with my birthday moms a few days before the show to say hello and review details. At that time I usually request a folding style chair be made available for my use.
Used while setting up and helps me get down closer to eye level with the kids for a couple of bits in the show.
At this recent party the artistic birthday girl went all-in leaving no doubt which chair was for me. She even added the (often overlooked) exclamation point to Mr. Oh!
Love it when I see this type of kid engagement. Not surprisingly this party was a joy to perform at.
