Some on-line collections are enough to make you want to throw up. Take the Air Sickness Bag Virtual Museum (www.airsicknessbags.com/). Not only can you tour one obsessive's collection of 1,800-plus bags (which includes vomit catchers for other modes of travel and causes of nausea) but you can even support his efforts by buying a poster featuring bags from around the world (”The one gift I guarantee your friends don't have”). Or you can just donate money to became a “Patron of Puke”. Some people's hobbies are so hard to chunderstand.
