"Gir, what is THAT?" Zim grumbled irritably, gesturing to the small green leaves dangling from the kitchen ceiling. He had had a difficult and stressful day, not really feeling like participating in whatever the robot had planned.
Gir grinned wide, eyes alight with joy. "It's a mistletoe!" He yelled happily.
Zim scoffed, unknowingly moving to stand directly under it. "Get that filth out of this house right now!"
His S.I.R. Unit looked up and smiled as he put his hands on his alien's face, catching him in a blissful kiss.
Zim returned the gesture, melting inside.
