In the two-part special called "Hey Baby What's Wrong?", it's Valentine's Day on the set of TGS. Liz decides to celebrate with her new beau Criss (wow, that does look bad), while Jack spends the Hallmark holiday entertaining his less-than-delightful mother-in-law (played by Mary Steenburgen).

Meanwhile, Tracy and Frank play Cupid when they spend the whole day trying to set Lutz up with the perfect girl, while Jenna is chasing her dreams on ever-popular America's Kidz Got Singing.

The hour-long 30 Rock event starts at 8 PM on NBC, followed by a new episode of The Office... but no Parks and Recreation -- boo!
