Hmmm people tell me I look like Edmund Blackadder, beats Baldrick I guess.

So many people here told they look like Rowan Atkinson's character Mr. Bean! Just proves the old adage "they all look alike to me" is universal.

It's easy to understand why Mr. Bean is so popular here: little/no dialog so no sub-titles to worry about and a physical humor which is quite popular here.

For the OP, what's done is done. Don't worry about the past. If Thai's choose to insult you they will do so in Thai, out of earshot.
