Always check before you sit down.
Have a good stick with the greenery still on it. Before sitting down push the greenery end into the seat hole and swish it all around the inside bottom of the hole to clear any Spiders and/or other critters and then bang the sturdy part around the seat to alert any Bears that may be in the WRONG CAVE while yelling “INCOMING, HEY BEAR, HEY BEAR INCOMING!!!”
(That could explain why some Bears are GRUMPY when they come out of their hibernation and find they have been getting crapped 💩 on while sleeping.)
