The signboard above was posted on Twitter recently and piqued the interest of thousands with its unusual presentations. Japan has a history of construction warning signs that might seem odd in other countries, with roly-poly penguins notifying us of gas line maintenance or a cuddly panda stopping us from falling into an open manhole.
This one, however, has even Japanese people scratching their heads. At first glance the sign appears to have a frisky looking construction worker telling you about his project with a saucy wink. However, the more one looks at this image, the deeper the rabbit hole goes.
