I'd also look out for two things...
First, make sure that the Teaser actually kills a chastised opponent. In my case if a teaser brings an opponent below 0 health, he is resetting to 1,000 health.
Second, if an opponent has a large amount of HP, and takes multiple animations for the Taekwondo Girl to kill... I am getting cash for each one of those animations. It netted me a lot of money next to a spoiled princess and I was loving it but probably not what you intended.
