In my day, anything that had the words 'naughty and nurses' , 'nude, boozing, and sorority' or 'bored, breasts, and some synonym or facsimile of the word vacuum (suck, swallow, gobble, inhaling, hose-loving)' in it. Then again I often hid a lot of hotel receipts instead making full per diem claims in those days as well. Adds up quick.
