American Dad! plays with this when Stan starts falling through row after row of dilapidated stairs while Steve takes a completely functional lift down at the same pace. At first, Steve is actually worried, shouting "Dad!!" a few times and loses a bit of enthusiasm each time until he starts saying the word in a monotone. Eventually he finds a newspaper and reads the comics while Stan continues to fall and crash through the wooden stairs.
Megatron finally using Optimus Prime's name in the "Endgame" finale - it means that he finally sees Optimus as an archenemy as opposed to just another Autobot nuisance.
Megatron: If I cannot save my clones, at least I'll have the pleasure of destroying you, Optimus Prime!
Optimus: So you can remember my name.
Megatron screaming Starscream's name is a recurring thing. In the IDW comics, it happens when Starscream is using Ultra-Energon to try and overthrow him. The juiced-up Starscream still gets EASILY pwned, and this Megatron will not be taking it lying down like certain other Megatrons.
In Animated Starscream tries to rig a MacGuffin to explode and destroy the Autobots and Megatron (and about half of Detroit would likely have gone with them.) Starscream fails.
Screamer: [Flying away at high speed] Sorry, you must have me confused with some other harrier jet! [Next scene is Starscream slamming into the ground. Hard.]
Transformers Cybertron, Megs gets booby-trapped and he and the 'cons loyal to him are left behind in a force field in deep space. Starscream feels the need to leave a message to make sure Megs knows who screwed him, and all Megatron can do is yell his name in fury.
In Transformers Prime, when Megatron finds out Starscream tried to off him in the premiere, rather than going for the traditional STARSCREEAM! he simply says his name quietly. However, his wrath is the same and he inflicts No-Holds-Barred Beatdown on him.
From Prime - in "Rebellion", Megatron lets out an "OOOPTIMUUUUSSSS!" while attacking in jet mode (having just been punched through his own throne by the newly-upgraded Prime).
In "More Than Meets the Eye: Part 3" of the original Transformers series, Megatron and the 'Cons are taking off in their space ship while the Autobots watch. Optimus reaches out his hand, and in one of Peter Cullen's greatest moments yells "MEEEGAAATRRROOON!"
In Beast Wars, the Maximals and Predacons are working together to stop the Vok from blowing up the planet. As Optimus goes to take out the Planet Buster, he realizes that Megs has sabotaged his shuttle and he won't be able to escape the impending explosion. Megatron broadcasts a message to him to taunt him about this, and Optimus yells MEGAAATROOON! just before 'kaboom'.
Henry on The Amazing Chan and the Chan Clan is prone to yelling Stanley's name when the latter is clowning around or goes missing. Stanley tends to call Henry's name whenever he gets himself into a scrape.
In the first episode, Helga is determined to ensure that everything goes right for the school play. When she notices that Arnold and Gerald's are missing on performance night, she shouts Arnold's name.
Arnold (on a bus): Did you just hear something now?
In the Halloween Episode, when Helga found out that the people are chasing after her and the others in alien makeup because of Arnold's prank.
