Today's edition of Stupid Panels of the Silver Age comes to us from "The Brave and the Bold" #29, May-June 1960, DC Comics. The story is entitled "The Challenge of the Weapons Master."

Xotar - the Weapons Master - has enslaved the Justice League but decides to release them one at a time to go on various challenges. He's from the future and has found an ancient journal entry, written by League Secretary Wonder Woman herself, that verifies that he will best the Justice League using one of his powerful and mysterious weapons. The thing is, he doesn't know which one, so he decides to travel to the past and test them out. Flash is up first.

Xotar gives him this clue:

When the ghost walks at Hesperus on the second day of the moonless month, I am waiting to do battle!

Four panels later, Flash has most of it figured out, the key element being the location of Xotar's attack, and then he hits the "moonless month" part...

Oh really, Flash? You think he intends to attack today?

Good work, Xotar! Way to keep the Justice League guessing! A time-travelling villain who decides to attack right now is definitely a candidate for Stupid Panels of the Silver Age!
