"No, you're not going to do that. You're just going to greet me, and say, 'take it away'," Kaimu said. "You're not meant to do that."
"Jessica, we are live," Kapunda replied, prompting a long and cringeworthy silence between the pair.
It is not clear what happened behind the scenes once the cameras stopped rolling, but it seems unlikely they would have broken out the tea and biscuits.
The exchange has gone viral this week after it was recorded by somebody on Twitter - and the responses are something to behold.
Lazarus Jacobs, chairman of the Namibian Broadcasting Corporation board, told CNN: "Unfortunately for the sports presenter, I don't know what happened in her earpiece, [but] she did not realise she was on air. What people heard and saw was something that was supposed to happen behind the scenes."
Surprisingly, he said there was no bad blood between the pair and they had a good laugh about the incident the next day.
"There was no disagreement of any sort. The two ladies are good colleagues [and] last night they had a live chat where they had a good laugh about it," Jacobs told CNN.
However, Jacobs said the pair had agreed to take part in on-air training. Contrary to online speculation, neither had lost their jobs.
