“You love him too, don't you?”

Is it, Whose birthday or Who`s birthday?

Last night I was flipping through the channels on the TV and I happen to catch Bill Oreilly reading the mail from one of his viewers. The person wrote that he saw him and Glenn Beck talking and it reminded him of Starsky and Hutch and Oreilly started laughing and said he was more like Huggy Bear. I thought that was funny and that it is true S&H is everywhere. I wonder which one was supposed to be Hutch and which one was Starsky, I just don`t get it!
