Spending long hours sitting in the corner of MPs' offices sorting through endless piles of claim forms and receipts.
I'm doing more of the same today - The Daily Telegraph must've had an army working on their investigation.
I haven't found a great deal among the receipts of various backbenchers I've been going through yet.
One renovated his bathroom for £4,000 another bought a flat screen TV for £750 - but after what we've seen that doesn't raise an eyebrow.
