* University of Hawaii-Manoa: Someone posted a sign outside a school building warning of a Malagasy biting cockroach infestation, the Ka Leo O Hawaii reports. Faculty also found orange powder outside the doors of three offices; the powder was later identified as powdered cheese.
* University of Michigan: At 3:10 a.m., students living in the school's largest dorm received an E-mail from the residence hall director's account detailing a severe asbestos problem that would soon close the building, the Michigan Daily writes. The message told residents to keep their windows open and wear protective masks, saying "90% of the (dorm's) pipes were found to contain asbestos on the outside, and 50% on the inside as well." A follow-up E-mail debunking the hoax was sent less than an hour later—calling the asbestos warning a "lame" joke and reassuring that nothing was wrong with the dorm. "At least not anything the E-mail said," the second message added.
* University of Wisconsin: More than 300 cars had their tires deflated in a combined political stunt/April Fools' joke. Many of the victimized cars—whose tires had BB gun pellets placed under the air cap—had the note "Happy Fossil Fools Day! Drive Less" stuck on their windshields. "It's more of an April Fools' prank which I'm assuming people aren't finding too funny," said a police official.
* University of Oklahoma: A law student placed letters in other law students' personal mailboxes informing them they had been accused of violating the honor code, the Oklahoma Daily writes. The letter was signed by the "Dean of Jocularity" and suggested students go to room 4302—a nonexistent office in the third-floor law building. Many students found the joke mostly harmless, but others called student services crying and one vomited after reading the letter. Meanwhile, the prankster—who was running for Student Bar Association president and also used the letters to urge his peers to vote for him—could be suspended or expelled for the hoax. The students declined to comment for the Daily, citing the ongoing SBA election. A panel also recommended that he issue an apology, be removed from the SBA ballot, and be barred from holding any student office.
