I know that it is a shame I couldn’t think of Samuel Beckett without help, but that’s the way it was. DQ for you.
Yes, I think it’s fair to say so.
No.

And here I was thinking of Saul Bellow, but Becket works as well.
Ok, my DQ: Were you a politician?
Do you have a guessing game named after you? 
Yes.
Were you a revolutionary leader who got no less than two countries named after yourself?
No, I’m not Sandro Botticelli.
Actually, I was thinking of taking Botticelli in the first place for the fun of it, the person I ended up with being just one of the possible guesses I was expecting. Before starting the game, however, I changed my mind, thinking that there are certainly enough would-be smartasses like me who’d think of Botticelli in a game of Botticelli.
You got it, so I’m just saying that yes, I am Simón Bolívar.
What’s the other country named after him? Are you thinking of the Bolivarian Republic of Venzuela?
Yup! Both Venezuela and Bolivia…
And hmm… does this mean I have to think of someone for #39?
In that case, cool
Congrats to Worm!
Just to tie up a loose end, the person I had in mind was Samantha Bee.
