Admit it. As you've worked on your tax return and considered what might count as a deduction, you've taken a few flights of fancy.

"The wedding gift for the boss's daughter as an employee business expense?" Come on!

We've uncovered what we think are the weirdest deductions allowed, ranging from pet food to free beer.
