He really seemed strange to me when I saw him at first, I have no clue about perl, but even to me he made some kind of impression, that he has not really done his research.

His character and presenting seemed really strange to me. I was honestly totally confused by his presentation and couldn't make out if this was supposed to be funny or if he is serious.

And if it was supposed to be funny, I didn't find it funny at all.

All in all, I was really irritated by his talk and avoided all his talks ever since.

reading your comments, it seems that was the right choice
