Depending on your perspective, April Fools' Day is either the highlight of the year -- or a great day to work from home. Even if you're totally anti the entire concept of April Fools', you have to admit that some pranks function as a kind of team-building exercise: something funny happens, everyone has a laugh and blows off steam, and hopefully, co-workers feel closer. Unfortunately, when pranks go wrong, they go really wrong, leaving a trail of hurt feelings and dented career prospects in their wake.
Ah, April Fools' Day: the day when some normally sensible professionals regress to high school students targeting a particularly reviled substitute teacher. It's bad enough that the entire internet now teems with fake ad campaigns and bogus products (although we did finally get that Tauntaun sleeping bag, at least). There's no need to compound your co-workers' misery with intra-office April Fools' pranks, as well.
