Job history

I've been with my current employer for almost 5 years and this is my 1st IT job. I am planning to apply to numerous large IT organizations and was wanting to know everyone's opinion on listing non relevant job history. I've had 4 jobs from the time I was 16 until ~21. My resume only includes my current employer and various roles.
What's everyone's opinion, add only the relevant job experience or provide a thorough list?

Otherwise, I'd say you are good just listing the one job.
Unncessary fluff or useless past experience tends to make me quit reading a resume.
This was for a companies online application. I think I am going to leave them off...I've had several fast food, houseboat manufacturing plant, retail management, to my current which is the only one with relevant experience for positions I'm looking for (although the retail management had some value with opening/closing a store, marketing, balancing drawers and paperwork)
Without them it looks like this is your first job and you did nothing from 16-21. While they may not have provided much relevant experience, they definitely speak towards your motivation and responsibility. I'd put them on but not really go into job responsibilities unless specifically relevant.
