The video of the IRS workers practicing their dance moves, which lasts just under three minutes, comes weeks after it was revealed that agency workers produced two other videos parodying the “Star Trek” and “Gilligan’s Island” TV shows.

All three videos were given to Congress on Friday in response to a request issued by Rep. Charles Boustany, R-La., a senior member of the House Ways and Means Committee, after learning that the videos were recorded at IRS offices in New Carrollton, Md., outside Washington, D.C.

The latest recording cost about $1,600 and was produced to be shown at the end of a 2010 training and leadership conference held in Anaheim, Calif., said IRS spokeswoman Michelle Eldridge. At a time when most government agencies are coping with across-the-board spending cuts by furloughing workers and finding other savings, that conference has become the target of a report a Treasury inspector general plans to release next week.
