Hahaha, I got a good laugh out of this because it reminded me of a cellphone call I had not long ago. first, a reminder;
“When I read in Chatlist #5202 Cryptik writing of gravel driveways and logic I thought that people might mistake Cryptik for me. After all, I taught logic (mathematical logic) at UNC for years and I now construct and repair gravel driveways. Some of you reading this know that.

So I affirm that I am not Crytik.

How can one prove this?

notice Mike claims he is not only NOT Cryptic but he is also NOT Crytic!
now to my phone call:
ring
me: Hullo?
caller: (pause)…Uh, is this Joe?
me: no, this is not Joe!
caller: this not Joe?
me: no, this is not Joe, I don’t know who you’re not…
caller: (pause)….laughter
me:laughter
after that we had a pretty good conversation and we still didn’t know who was who but we know we were NOT Joe…
