Thank God You're Here/Funny

ALL of Frank Woodley's performances deserve special mention, as with the time Shaun Micallef tried to bring Shane in to the sketch.

Student: You once said an apple is harder than a stone but softer than a feather... ...What did it mean?
Frank as a Shaolin Monk: That means that all things have a beauty, but all things indeed have an ugliness. You must understand the paradoxes of this world. Don't try to eat a stone. You - It'll hurt.

Three words: "Nah, mate - LEGEND!"
Hamish Blake is the master. His caravan performance was so good that Niki broke character.
The show spawns these once an episode, or once every three seconds if Angus Sampson or Frank Woodley are involved. A recent example is Colin Lane, dressed up as a heavily pregnant woman. As soon as he had to say something, he put on the deepest voice he possibly could. It lead to the following exchange:

Merrick Watts as an Obstetrician: Obviously you don't want to give birth as a male.
Colin: You wanna start something, mate?

Frank's Crowning Moment is when he was a Shaolin Monk. Because Frank pretty much epotimises the Digging Yourself Deeper trope, this happened:

Student: You once said an apple is harder than a stone but softer than a feather... ...What did it mean?
Frank: That means that all things have a beauty, but all things indeed have an ugliness. You must understand the paradoxes of this world. Don't try to eat a stone. You - It'll hurt.

Considering that the idea of the show is to give the guests as little power as possible, Josh Lawson is able to control any scene he's in incredibly easily and make it hilarious. Here's one. and here's another. Seriously, words just cheapen it.
- The most striking demonstration of his ability to dominate the proceedings came later, in this indescribable skit.
Matthew Newton is king of TGYH's unusual entrances. Coming out of a car that had crashed through the front window of a house, the sight itself is just so unbelievably funny but the best part was easily when he was questioned about his "L" plates (for overseas Tropers, L stands for Learners and is the first stage of license holding here in Australia) His response? "Nah, I'm a LEGEND!"
Bob Franklin playing an RAF captain, who takes the scene Off the Rails early on by claiming that their target for a bombing raid is Target stores, and then thanks his costar for railroading him back to the script. "Well played sir. Back on track."
- He does something similar in a later sketch, in which he's asked to explain why a tea lady named Irene is being made "put down" as he described it. He starts strong - "For starters, you're drinking too much water," immediately after Irene had picked up her glass. "Secondly, you've been turning up a little late, haven't you? Just lately..." His costar interrupts, saying "But most importantly..." He continues, "Most importantly - I'm glad you led away from that, because it was going nowhere."
Ross Noble's reaction to the dwarf coming out of the log and the reason he seems so confused when he finally gets out.
