Punk Rock is Your Friend: Kung Fu Records Sampler #4 is the fourth
compilation album by the
Seal Beach, California record label
Kung Fu Records, released in 2003. It features artists signed to the label at the time, as well as others who were not signed to the label but had participated in some of their releases such as The Show Must Go Off! live
DVD series. It was the first of the label's samplers to use a number in its title, as it was the first to repeat the "Punk Rock is Your Friend" title. Interspersed between some of the tracks are clips of comedian
Neil Hamburger from his
Kung Fu Films release Live at the Phoenix Greyhound Park. It is an enhanced
CD-ROM that also includes several music videos.
