Is it the episode when the lady caller claimed that she was proposed to in a restaurant? When KS began to question her ie. Where were you guys sitting? What did you eat? What location did you go to? Etc.
When she couldn't answer quickly enough, he shrieked, threw his arms up, & told her to get her lying self off his phone, hung up in her face...then made a follow up or 2 videos explaining his actions?
He backed his reaction & subsequent actions up w/the following explanations:
1. Majority of women will remember, recall, & recount every single detail of a proposal. Every detail.
2. He knows the Manager & location very, very well of the restaurant she said she was proposed to at...
If this isn't the episode and you're referring to another similar incident then he really can't stand a liar. I can't blame him.
Also, he has the patience of Job with many of those callers - many of them are extremely annoying & gluttonous for mistreatment.
