me: check this out
person: its funny, but why would I want my number on a teeshirt?
me: well, its not really yours, it's an anonymous phone number you can forward to your cell, email, or set an auto-responder
person: OOOOHHH, thats pretty cool!

person: hrm..I am not sure, but I could see it becoming "a thing"
me: perplexed on whether to invest time and money into this.
