(FoxNews) - Another government watchdog report has flagged inappropriate behavior at the IRS, this time claiming government credit cards were used to make questionable purchases on items ranging from wine to online pornography. 

The report from the Treasury Inspector General for Tax Administration found that between fiscal 2010 and 2011, the more than 5,000 IRS card accounts racked up $103 million in purchases. 

"While the majority of IRS cardholders appear to use their purchase cards properly, TIGTA's audit identified some troubling instances of inappropriate usage," J. Russell George, the inspector general, said in a statement. 

The report said the cards were at one point used to pay for a dinner that cost roughly $140 per person -- four times the amount allowed by federal rules. They were also used to pay for a lunch that cost about $100 per person, five times the allowed amount.   

The report said IRS credit cards paid for 28 bottles of wine at the 2010 luncheon for tax officials from other countries. There were 41 guests. 

In another case, cards were used to make questionable purchases of decorative and give-away items including plush animals, bandanas, kazoos and a rented popcorn machine.
