Whether brilliant or outrageous, we rooted for these guys. There's more Shark Tank pitches to root for Tuesdays & Wednesdays starting at 8p EST on CNBC!

1. The shrimp burger that the Sharks still cry about.

abc

The Sharks couldn't get enough of Chef Big Shake's shrimp burgers, but when the time came to invest, they didn't bite. Chef Big Shake has since made almost $6 million, and the Sharks have cried six million tears.

2. The pet paint that launched a dog fashion show.

abc

The Sharks were wary of Pet Paint's colored hair spray for dogs, and though the dog fashion show stole their hearts, it didn't quite empty their pockets.

3. The water balloon filler who called Barbara Corcoran "baby."

abc

Tie-Not piqued Barbara's interest with a patented water balloon filler that would save parents valuable time. But pushing back on her offer was the wrong move.

4. Slawsome Slawsa!

abc

Slawsa, a cross between salsa and coleslaw, had a great name, a great play on words, and a great pitch! But, sadly, condiments don't have much appeal to a Shark.

5. The counteroffer for a wine by the glass that got the quickest "no" ever.

abc

Kevin O'Leary wanted his hands on Copa di Vino's wine-by-the-glass patent, but his offer was shut down. Upon hearing the counteroffer, he was out faster than you can uncork a wine bottle! The most tense pitch in Shark Tank history.

6. The sweat-activated technology that had its creator, well, sweating.

abc

ViewSPORT's sweat-activated apparel was intriguing: a shirt which slowly reveals a motivational message the more you sweat. But a malfunction in the product made it an easy no.

7. The pain blocker with the enticing profit margins.

abc

Everyone was interested in Buzzy, the device that blocks pain during injections — even moreso once they heard how profitable it was! But asking for 27 times the company's earnings scared every Shark off for good.

8. The professional wrestler turned yogi.

abc

The WCW wrestling champion's flexibility spoke for itself, but the Sharks just weren't flexible enough to invest in DDP Yoga's online yoga videos.

9. The time Kevin O'Leary got dramatic over a travel guitar.

abc

Voyage-Air Guitar was one of the coolest products pitched on Shark Tank — a travel guitar you could fold in half! But when Kevin O'Leary's offer was shot down, he became one big drama queen.

Voyage-Air Guitar was invited back on the show and finally did strike a deal with Kevin, making it the first time a Shark ever swallowed his words.

10. The fart-scented candle.

abc

Who could forget Original Man Candles, with scents like bacon, barbecue, and... farts? This one doesn't need much explaining. Lots of laughs, but no deal!
