Get the jamster mug.
probably the most annoying commercials ever created with the most retarded ringtones and wallpaper for your cell phone. created for fucktards of america.
you might find yourself ordering the 'sir mix a lot' ringtone while very drunk or stoned late at night watching mtv, then you wake up in the morning and feel like you have been cheated out of life.

drunk person: "man last night i think i got jammed"

Annoying little shit-tard of a mobile phone/ring tone commercial company that has taken over the world and infected our homes and the streets with the ever annoying "crazy frog"! jamster likes to appear on T.V every 2 minutes with its creepy necropheliac frog with a teeny prick and a retard helmet singing like a freakin grand prix race. Crazy frog (aka Axel F) has even made it to #1 here in Australia and in the UK music charts!!! (sad but true! ) aghhh...god help us!!!!

Ringtone, wallpaper and other crap internet business which
targets children and then makes it incredibly difficult to
unsubscribe from their service. Texting STOP doesn't stop them from stealing money from your mobile.
Want to get back at Jamster ?
Got broadband ?
get something called wget (free, part of cygwin) and
set up a loop that continuously does
wget -r www.jamster.com
or wget -r www.jamster.co.uk
Waste their bandwidth. Hit them in the pocket!
Get enough people to do this and they'll get the message.
Jamster steals money from kids

Retarded cellphone ringtone provider with irritating commercials and VERY unfunny songs and sounds. People who have ordered ringtones from Jamster can be found on the short bus or working in Wal*mart.
