How do you pronounce Coke?

I should say I have a lot of respect for anyone who learns to speak a second language, but I can’t help but laugh at the unintentional mispronunciation of “Coke” in this video.

This well meaning Korean teacher continues to  pronounce the word “Coke” as “cock” and asks her students questions like Do you have a coke/cock? and How much is this coke/cock?  It is incredibly juvenile I know, but it is also funny.
