Jason John Whitehead

The laid-back Whitehead, defined by his rock apparel and sleepy eyes claims to have worked hard over this year's show: 'it's got a theme; it's about being a comedian.' This is typical of the Canadian's easy-going style and enjoyable performance, but don't be fooled, his mind may be fuzzy but his material can be deceptively cutting.
