Cmon you don't remember all the Jamsters commercial. Text us 1343 for the Dancing Baby wall paper, Text 3456 for the Flava Flav wall paper with gold spinners on his teeth. Or txt 3425 for wallpapers from the latest 14 year old we dress up as a prostitute and call her an artist. Text Now!




















texting numbers to this line you agree to unlimited charges on your phone bill and theres nothing your 99% arse can do about it. Suck it,
Sincerely,
Jamsters
