Swing Set

注意、天気の良い日は熱くなっております。
ちゅうい、てんきのよいひはあつくなっております。
Warning, on days with good weather, this will become hot.

Some signs are useful and some are just funny. This sign was on a large, arty swing set in the park behind Tokyo Midtown. You would think that if you were designing play equipment, you would make sure said equipment didn't become blisteringly hot on sunny days, you know, when kids are likely to play on them.
