Tiernan is a very funny comedian. Some of his material and takes on Irish life are very very clever.
Hes not perfect so internet haters are always going to jump on that. The internet hates comedians. When you say 'hes not funny' you actually mean 'hes not funny in my opinion' and your opinion is up against the most successful and wealthiest Irish comedian of all time. He does runs of 25+ in large Dublin venues so your opinion, while youre entitled to it, is wrong in many peoples eyes.
Yeah you're right.
Spastics find him funny.
