More misguided software proposals!

Microsoft should add a new program to its Office Suite: Microsoft Time Traveler. To prevent errors in causality, the only thing it will let you do is deliver a swift smack upside the head to previous users of whatever Microsoft Program you're working with. Someone managed to enter 1500 records without noticing that the units of measurement varied between entries? Someone included 200 superfluous columns from Excel in your database? Someone (usually you) deleted a table when it was the only soft copy of the data you needed? Use Microsoft TT to punch your past self in the ear. Bastard.
