No matter how much we say we hate it, Jersey Shore never ceases to amaze. Ronnie having tearful, emotional meltdowns? Pretty incredible. The grenade whistle? Epic.

Here's last night's episode in a nutshell: JWOWW and Snooki walk in the house with two dogs. The Situation quickly realizes he's amongst the company of a grenade.

Vinny sounds the grenade whistle, which is more like a grenade horn, to rescue The Situation. Ronnie flips out and throws Sammi's belongings all over their room.

MVP D: Deena Nicole Cortese is the show's Rookie of the Year.

Vinny is shocked when his hook-up's family arrives at the house. JWOWW worries Sammi will catch her consoling Ronnie. Sammi does, and slugs him in the mouth.

The roommates surprise Snooki's friend Ryder with a birthday cake. Aww. Vinny, Pauly D, Snooki and Ryder try to calm down Sammi. Ron Ron breaks down in tears.

Snooki and Vinny decide to buy a stripper pole for the house. A newly-single JWOWW grows closer to Roger. Deena confronts "Fake Ronnie" for spreading rumors.

JWoww and Sammi decide to try to mend their friendship. We'll see how that goes. Plenty more observations and some Jersey Shore quotes from last night after the jump:

The cast has always sought to nix the less-than-desirable women they invite back, so the grenade whistle was a fitting, tasteless, hilarious, long overdue touch.

When Snooki buys a stripper pole, her gut feeling is that her dad may not be thrilled when he sees it on the credit card bill. Yes, her dad still pays the thing.

"I hope when I wake up you've written me a f---ing book of apologies!" Ron yelled. "Yeah, go on. Keep crying. Your f---ing tears mean f---ing di-- to me."

Regular Hallmark card.

Sammi should be charged with assault. Amber Portwood has been, although there was a minor present in that situation. Snooki could pass for one maybe?

Deena has some interesting tastes when it comes to sex stuff. That's as much as we're going to get into it here. Enjoy some of the top lines from Thursday:
