Jake has proven to everyone he is just a naïve fool. A TEFL is an "education"? .

Yes,. most likely his TEFL course provider includes modules how to act as a white monkey in a muppet show as a part of the programme. In that case, their demo class looks a bit like this:

(TT-TEFL trainer, S1, S2, etc.= course student):

TT: In this class today, you will learn how to make your class entertaining and to motivate students to use English. One of the most frequent ways used is role play. Let me show you how this could be done in class by making use of an exciting topic. This will be a mock class, you will take the student role, and I will take the ESL teacher part.

S1: May I suggest an exciting topic?

TT: Oh yes, make students suggest a topic that interests and challenges them rather than set it for them.

S2: Fine, what about monkeys in a muppet show?

TT: Excellent topic. OK, now, here we go.... Fist of all, let's think about what is needed for the plot.

S3: Monjeys,,,so let's act them...

TT: Obviously, you will also need tress and bananas.

S4: Yes, and banana leaves, too.

TT: And a training centre that provides the stage to perform the show..........Uauauauauauauaua....brrrrr......

S5: hahahahaha....let's mocjk a monkey's,voice....IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIeeeeeeeeeeeeeeeeeeeeee..........

TT: Uauauauauauauauaua.....

S6: Niow, we still need to imitate the sound that monkeys make when eating bananas........ggggggggggggggggggggggrrrrrrrrrrrrr..plopppppppppp......hahahaha

S9: Some monkeys also are known to steal scotch drinks from foreign tourists at the beach of Thartaplatyaja in Thailand......

TT: Right. After drinking and emptying the glass, these monkeys become easily drunk and start singing like this
(intunes melody and imitates singing the song) It is a long way to Tippirary....hicks....ooohhhhhhhh....a long way to go.......hicks......ggrrrrrrrrrr....uuuuaaauuaa.....God shave ourb gracious Queen, she lives in Aberdeen.....uuuuuuuuuaaaaaaaa......hicks....ggggrrrrrrrrrrrrrrrr.....ooooooooooh...

(Students join in th chorus and imitate the behaviour of drunken monkeys)

etc. etc,

A good, entertaining and effective TEFL lessin indeed....lol.....LOL
