"Look, before the needle touches your skin, I just want to be absolutely sure: do you really want a tattoo of a Powerbag?"
"Yes! I've thought it through, I'm over 21, I can pay good money, and I want a tattoo of the bag with the built-in battery system to charge USB, mini-USB, micro-USB, and 30-pin devices."
"I know, I know, the Powerbag sounds great... I'm just saying, tattoos are for life. So if you have any doubt, any doubt at all, like maybe that someday a better charging bag might come along-"
"A better charging bag? No way. How could you possibly improve on a backpack that keeps your devices juiced up AND has room for a 16" laptop AND has a tablet compartment? You're a great tattoo artist, but you'd never make it in the electronics biz."
"Fine. It's your skin. Do you want the black messenger-style bag, the grey messenger-style bag, or the red backpack?"
"Surprise me. No, no, wait: all three."
"OK. And where do you want it?"
"Uh, I'm sorry, but we don't tattoo there. That area is way too sensitive."
"Aw, come on! Where else could possibly be more appropriate for a tattoo of a Powerbag?"
