There's always going to be a demand for celebrity memorabilia, but some people are simply taking this too damn far.

It's one thing to want a prop used in a music video or a microphone from a tour. It's way more extreme to go after someone's snotty tissue or half-eaten breakfast. Or the dirt from their neighborhood, which someone in Justin Bieber's hometown of Stratford, Ontario is now selling for $40 a jar! And it gets way pricier from there. Some fans paid more money for these items than most people have in their checking account! Check out our roundup of the 10 weirdest celebrity items ever purchased!

Apparently, Justin's half-eaten french toast constituted bringing sexy back for one fan. The fan, who was a teenager when the auction took place back in 2011, paid $3,154 on eBay for the breakfast. No word on how that french toast is doing 11 years later.

2. Niall Horan's Half-Eaten Vegemite Toast

If you thought boy band fans were rabid during the '90s, you haven't seen One Direction fans today! Not only that, but they've got more money to blow. Someone bought Niall's half-eaten toast with vegemite spread on eBay for $100,000!

3. Scarlett Johansson's Snotty Tissue

While appearing on The Tonight Show With Jay Leno in 2008, Scarlett blew into a Kleenex and said she'd auction it off. It's unclear whether or not she was kidding, but a silent auction took place and the winning bid went for $5,000. Luckily, all the money went directly to hunger charity USA Harvest.

4. Justin Bieber's Hair

How much does it cost to have a piece of Justin with you forever? If we're talking a lock of his hair, then $40,668. Justin gave Ellen DeGeneres the item while appearing on her show to help raise money for an animal charity. Even more ridiculous? 98 people engaged in a bidding war for the hair!

5. Brad Pitt and Angelina Jolie's Breath

Someone who might be a little messed up in the head paid $523 for a jar of Brangelina's breath. We have to wonder if he resisted the temptation to open the jar and inhale.

6. Michael Jackson's Underwear

Would you want Michael Jackson's undies that were used as evidence in his child molestation trial back in the '90s? No? Well, apparently there's a sick bastard who did. Not only that, but he paid $1 million for the tighty-whities!

7. Britney Spears' Gum

Here's the closest any of us will get to playing tonsil hockey with Britney. In 2004, her used chewing gum was sold on eBay for $14,000!

8. Madonna's Flirty Voicemails

Here's one weird celebrity item that might be worth the money! A series of flirty voicemails she left for her ex-lover/security guard in the early '90s sold at auction in 2009 for $25,000!

9. Lady Gaga's Teacup and Saucer

A teacup that Lady Gaga used at a press conference in 2011 raised $75,000 at an auction last May. The teacup includes an autograph from her that says "We Pray for Japan." All the money raised went directly to an arts fellowship program in the country.

10. Marilyn Monroe's X-Rays

Everyone wanted to see Marilyn's chest back in the day, but this was a little extreme. In 2010, a man bought three X-rays of Marilyn's chest that were taken in 1954. The item was expected to fetch $3,000, but ended up raising $45,000!
