At the Seattle P-I's Big Blog, blogmistress Monica Guzman shares several ideas from readers re: April Fool's Day pranks, including: "Put a package of cookies in a trash can. As people walk by, pull out a cookie, and say "Wow, a perfectly good cookie!" Then eat it." And: "I set my co-worker's Microsoft Word auto-correct feature to change "the" to "teh" and "a" to "an" as she typed." Remember: Tomorrow's April 1.

Question: What is the best April Fool's Day prank that you've pulled?
