maybe it's just me, but i would be embarassed if i was his children! 1) to see my dad acting "that silly and crazy up on a stage and 2) perhaps my religious upbringing and morals but also if was his children i would be embarassed and kind of weirded out to see my dad 99 percent naked on stage in a thong!
of course depending on the age of the children, maybe that doesn't even cross their mind, although i think it would be like a young kid seeing their parent walking around the house in their underwear which i don't think is appropriate unless the child is like 2 to 4 years old and doesn't know anything yet.
