Racist my as$. That's just funny. Like the credits read at the end of "Car Talk" that thank the legal team of Dewy Cheatham and Howe, or the researcher Marge Innoverra. Sum Ting Wong, indeed.

There is a remarkable difference between the example in the OP and the example offered here.
 
The Car Talk example offered here is a clever use of familiar syllables and it leverages some stereotypes of professions.
 
The example offered in the OP is a ridicule of a stereotype of the speech patterns of a population of humans that grew up speaking another language. It isn't a joke about the airline profession, it is a broad based implication that leverages a long standing and insulting stereotype based on one culture's estimation of another culture's ability to mimic its speech patterns.
 
It was clever, but I doubt I'd find it funny, even if it was part of a light hearted stand up comedy sketch.
 
Making fun of people and how they speak seems lame.
 
 
 
In the context of this circumstance I personally don't see how it can be funny.
 
 
all the best,
