The Lions began their 2008 season at the Georgia Dome against the Atlanta Falcons. A pre-season poll on thespread.com said the Falcons (who finished 11-5 before losing in the Wild Card round of the playoffs), were less likely (dead last for that matter) to make the Super Bowl than the Lions. In the first quarter, Detroit trailed early as rookie QB Matt Ryan completed a 62-yard TD pass to WR Michael Jenkins, while RB Michael Turner scored twice on runs of 66 and 5 yards.  In the second quarter, the Lions responded when rookie RB Kevin Smith scored on a 3-yard TD run, while QB Jon Kitna completed a 21-yard TD pass to WR Roy Williams.  However, in the third quarter, Atlanta continued its dominant start when kicker Jason Elam kicked a 50-yard field goal, while RB Jerious Norwood scored on a 10-yard TD run.  Detroit replied when Kitna hooked up with TE Casey FitzSimmons on a 1-yard TD pass.  The Falcons sealed the win in the fourth quarter with an Elam 25-yard field goal.
Question: How many total yards did Jon Kitna throw for touchdowns?
Answer: 22
