- "Well fought. I concede."
- —Rexxar, the Hunter hero in Hearthstone.
"Pulling a Hartung" is an in-joke for fans of Scotch and Smoke Rings, essentially meaning to concede in a game of Hearthstone. It is a reference to long-time fan, Federo Gregoro, often conceding to Oxhorn in the game when he knows he has lost. This is polar opposite to Ox who never concedes to an opponent.
- "What?! Mal'Ganis?... I'm about ready to pull a Hartung here ladies and gentleman."
- —Ox nearly pulls a Hartung of his own against Gentleman Badger.
- "Oh! What? You've got Thaddius on the board and you'd pull a Hartung?!"
- —Ox shocked at Greg Hartung's concession on Episode 308.
- Oxhorn once nearly pulled a Hartung while doing battle with Mal'Ganis. He has otherwise never attempted to concede in Hearthstone.
- The phrase has become so iconic that other fans sometimes refer to Oxhorn simply losing the match as "Pulling an Oxhorn"
