Sometimes You Have to Work on Christmas (Sometimes) is the second EP by Harvey Danger.

It was released in December 2004 on the band's own label, Phonographic Records.

The title song was originally recorded for Santa's Swingin' Sack, a 1998 CD compiled by Kevin and Bean, a disc jockey team for Los Angeles rock station KROQ.

Though as of mid-2005, this EP was out of print, the band re-released it for the 2005 holiday season.

Some copies purchased through the band's website were accompanied by a Christmas card signed by members of the band.
