Blind Hearts Puns

I was at my friend's poker night and we were playing texas hold 'em. On one of the hands the flop was a 3 of spades, a 7 of clubs, and a 2 of hearts.

Nobody really had anything so far and the hand went:

Friend 1 (small blind): "Check"

Friend 2 (big blind): "Check"

Friend 3: "Check"

Friend 4: "Check"

Friend 5: "Check"

Friend 6: "Check"

Me (dealer): We must be in the Czech Republic
