Idiot Overlord: "You can't best me! I know all of your tricks!"
The four spies in the room and the four spies outside looking at each other: "So...who's going to tell him?"

Sauron:*walks in* they never suspected a thing boss

"Im taking your fort."
"Oh yeah? You and what army?"
"Me and your army."

“I won’t need any tricks to beat you”

has four spies planted in the throne room

Overlord gets up: "Brilliant idea boss, they never knew what was going on!"

This was less of an siege and more of an extremely elaborate eviction.

That one bodyguard who isn’t a spy:
"Great plan, boss! They never realized I’m on your side!"
Talion: "... do I know you?"
Orc: (starts sweating)

Overlord's wife walks out
"Good plan boss, they 'ad no idea"

If I was the Overlord I would also go "arghh" and turn blue and hope no one notices.

"bro it's battle day, why are you painted in blue and not in red ?"
"idk bro I like blue that's all. Watch your back during battle"

Warlord: 'Oh for crying out loud, is there anyone here, NOT on his side?'
The fort cook coming out of the kitchen
'I didn't want to make a fuss, buuut.'

Literally god himself walks into frame
"Good job boss, didn't even suspect a thing"

“I know all your tricks, Gravewalker.”

“Ever heard of Julius Caesar?”

that overlord basically said "years of Acedemy training waisted"

Melkor walks in “excellent plan boss they never saw it coming”

I like the idea that none of the spies realized each other were spies too, they all hid from each other and the overboss thinking they were the only one

'i won't need tricks'
proceeds with the deception, infiltration, betrayal, slow motion and poisoned weapons
oh talion, you're such a cheeky bastard

Sauran climbs down from his throne stepping forward
Sauron: "brilliant plan boss, they never saw it comin."

It was hilarious how everyone just started popping out of nowhere and started congratulating themselves.

After those capture points and spys. I half expected the warlord to rise up as he entered with a "just keeping ya seat warm boss"
