Divot

"See you in a few seconds lads!" Cumslap hopped into his time traveller and dialled in a few weeks ago
His minions looked on as the device flickered in and out of existence
Cumslap zapped into the past and began carving his name across as many walls as he could find
The minions rubbed their eyes and fondled the divots in the walls
They couldn't believe what they were seeing!
"cumslap woz ere" suddenly started appearing all around them
Later this might seem like a bit of a tactical error
But for right now Cumslap was loving it
