Most of the rest of the world would have no idea who most of these people are.

R18 OK... I offer up Cheryl then.

Jim - there's only one.

[quote][R18] OK... I offer up Cheryl then.

LOL - does that count since we have no idea what her last name actually is?

Donald

R21 Her full name is Cheryl My Pussy Stinks, natch.

R7 there’s only one Michelle in my contemporary experience. Same with Nancy. I would expect a surname with the others you mentioned, otherwise my assumptions are as stated. But I primarily follow political news, so I understand my references are skewed.

It doesn't count if it only works for you particularly.
