Green traffic cone
From A KoL Wiki

green traffic cone
This is a big cone of bright green plastic. You have no recollection of how or where you got it, but it's like I always say -- it's not a good night unless you end up with a traffic cone!
This cone would've been far less effective back in the days when the roads were paved with grass. Which is to say the days when there weren't any roads. So I guess they didn't really need traffic cones, anyway.

Notes
- This item appeared in players' inventories the next morning if they had seen the To the Rescue stupor adventure, available by adventuring in a St. Sneaky Pete's Day Stupor on St Sneaky Pete's Day IV. The adventure would only occur if they were wielding a cheap plastic bottle opener.
