comment Ingenuity in mathematics
To complete the triviality of the situation, after your audience proposes a bunch of complex strategies, propose an alternative game whereby after "STOP" it's the last card in the deck that gets turned over. Everyone sees that this game is strategy-indifferent, and then you deliver the coup de grace... I've used this several times in math circles. Gets them every time.

comment 4-colorable graphs
It's even falser :-) In fact, there are graphs with high girth and high chromatic number. A graph with high girth looks like a tree around any vertex, so it avoids much more than just triangles. Proving that such graphs exist is perhaps even simpler than the explicit construction by Mycielski; it's basically a counting argument.

comment Approaches to Riemann hypothesis using methods outside number theory
Is the "hidden operator" approach initiated by Dyson and Montgomery subsumed in the the Bost-Connes approach? en.wikipedia.org/wiki/Hilbert%E2%80%93P%C3%B3lya_conjecture

comment How thick is the reciprocal of the squares
In the OEIS entry there's a comment by Frank Adams-Watters citing your paper. The first statement in the comment is "This set has zero density". Presumably this is wrong, and worth correcting? research.att.com/~njas/sequences/A108345
