That is Priceless by Steve Melcher for October 12, 2017

Look, you lot, this is not casual Friday! Put some bloody knickers on!

I’m having trouble seeing this as a catapult, particularly as the guy up the steps seems to be holding a red hot projectile, as might be shot from a ballista.

The naked alt-right failed to slip their trebuchet into Charlotte today.

When clocks were first invented they could be a bitch to wind.

RUN!!! They have a weapon that will blow your shorts off!!!

F**king Logistics! Where are those damned uniforms?

Knock three times on the ceiling if you want me……..

" Note To Self: NEVER hire your nephew to be the Siege Engineer !! "

Don’t let go or this guy’s going to get it right up the a**.

What? They said that today, we tan our hides.

has the prior work (which, sadly, still has all the 13 hyperlinks in my comment, plus who knows how many in my replies, there, inactive @#$%&!).

Again, a larger strip image is shown by clicking the image in Mr. Melcher’s MASTERPIECE #1781 (October 12, 2017) blog entry, accessible by the Check out the blog! box after the last comment; so, I won’t point to it here.

am I the only one who likes to be nude?

Bob was just not very good at “strip-siege-engine-arming.” He was always the first one out of his underpants.
