"The Hill Giants sent their 'elite' guards again."
"Oh fantastic."
"Yeah, and it'll cause another diplomatic uproar if we put them on kitchen duty again, sire, but don't worry...I have a plan."
"Sure. Let me hear it."
"I can send them to guard the outermost doors. We're not hearing of any hostile activity right now, so it's a cake job. They stand outside, together, where they don't bother the rest of us."
"I like it so far. Go on."
"Even if something does happen - which I highly doubt - we'll have enough other capable warriors inside that should be able to easily finish off whatever they soften up. We won't risk any real Giant blood in the process, and the Hill Giants will get a big flowery certificate - written by me, Your Majesty, all you have to do is sign it - that they can put on their wall as bragging rights. You know how much the tiniest little notice from us does to their morale."
"Mmm, clever."
"The best part, your Majesty, is they stay outside, so they don't ... um ... pardon your majesty, but there is no delicate way to put this-"
"Just say it, I come from military stock, you can't offend me."
"Thank you, majesty. They won't stink up the hall with their atrocious body odor. The last feast, nobody within ten spans could even eat. And we had to burn the pelts they sat on. The others will be...grateful."
"Excellent thinking. Make it so."

Everyone here with their serious games with elite guards can keep their games.
I like some whimsy, opportunities to explain why a single small band of small humanoids can defeat a far superior force, and creating 'fatal flaws' in the plans of would-be conquerers. There's a reason lists like 'If I Was An Evil Overlord' exist, and it's great fun to go through that and put a few of those exploitable flaws into adventures.
If the Bad Guys[emoji769] were really always that smart and together, then they'd win. Hubris, incompetence, overthinking, doubting the wise words of smarter underlings...these are all the unmaking of a BBEG.
