I watch this when it's on but mainly only to laugh at the dumb ideas a lot of the clients have for tattoos. There's always someone who wants a fairy or something, but they want to make it mean something as a way of justifying the tattoo, so they'll stick a horseshoe or a four leaf clover on it, just get the fairy for aesthetical reasons instead of ruining the design by shoving something totally random on it!
I kinda dislike the fact that the 'clients' have been through a casting process before getting an appointment, it always seems so scripted.
