GOOF: During the Gibb's first flashback of him and his Father, we see Gibbs around the age of 6 walking through a water puddle holding his Father's hand. As Leroy Jethro Gibbs' birthday is May 2, 1958 ("Heartland", episode number 117, season 6, episode 4), this would put this scene around 1964. The goof comes from the pair of shoes he is wearing, as they clearly could not exist in the 1960's. He is wearing a pair of Converse Chuck Taylor All Stars sneakers. In the 1960's the heel logo was a dark blue/black with multiple stars (one large star with 2 smaller stars on either side). The pair of Chucks young Gibbs is wearing has a white rubber logo with black lettering saying "ALL STARS." This logo and its variations didn't start till the late 1980's a full 20+ years later.
McGee: Abby, Gibbs is gonna appreciate whatever we send. There's no reason to stress.
Abby: I have to stress... because if I don't stress, then I'll stop and if I stop, I'm gonna get really, really sad.
Bishop: When my grandma died, it helped me just to talk about her. Maybe you guys could tell me what Jackson was like.
Abby: He gave the best hugs.
McGee: He was the only one that could do the "Gibbs stare" at Gibbs.
DiNozzo: With those icy-blue eyes. He gave me the sweater off his back once. White. Two functional pockets. Very soft.
