Holzhausen, Germany

The German Bratwurst Museum is the first of its kind in Germany. Providing visitors with everything they might want to know about the sausage-making process, the museum displays machinery and equipment. Visitors can also learn about the history of this iconic food, including that the first mention of bratwurst occurred in 1404. The museum also boasts a model of a traditional German festival, which is synonymous with the bratwurst. And to pay real homage to the bratwurst, the museum also houses a collection of other bratwurst memorabilia.

Plano, Texas

The brain-child of pest-control expert Michael Bohdan, the Cockroach Hall of Fame is located inside Bohan's store, The Pest Shop, in Plano Texas. The Hall of Fame displays dozens of various types of cockroaches both dead and alive. The highlight is displays of "roach art," made from dead roaches donated by a wide variety of people. One of the most notable pieces was created by an 85-year-old lady from Fort Worth, Texas, who placed a dead roach next to a tiny piano dressed in a mink cloak. She named him "Liberoachi."

New Delhi, India

Displaying toilets from as far away as Argentina, Luxembourg, Kuwait and Senegal, the Sulabh International Museum of Toilets provides visitors with a unique look at the history of sanitation across the world. The museum aims to not only educate people about "the historical trends in the development of toilets," but also provides help to "manufacturers of toilet equipment and accessories in improving their products." Either way, objects in the collection include pre-Victorian chamber pots, ornate royal "thrones" and the ingenious microwave toilet which used less water in hopes of revolutionizing the experience.

Amsterdam, Netherlands

Set in Amsterdam's red-light district, this museum is not for the faint-hearted. The Torture Museum lives up to its name with dark lighting and an entrance that sees visitors begin their experience by journeying down a dark corridor. The exhibit includes a historical tour of various torture methods, primarily focusing on those from medieval times. Devices on display include the inquisition chair, the skull cracker, the heretic fork, various hanging cages and masks, and, of course, the guillotine.
