You can download HeckleWorks Pro 4.0 for Mac from our software library for free. The application relates to Lifestyle Tools.
From the developer:
HeckleWorks is a robotic heckle, jibe, insult and realtime personality evaluation generator. Cut, copy and paste are fully supported, making HeckleWorks an ideal tool for filling evaluation forms.
The "Yell Continuously" function generates a constant stream of heckles, and speaks them with a variety of voices.
Time sliders allow the user to set up intermittent heckling, lying latent in the background.
