i beg to digress - You say something stupid, but you think it’s clever and you

You say something stupid, but you think it’s clever and you keep going even when people look confused.

I beg to digress, I’m clever, so I’m going to keep talking.

I beg to digress, I’m not stupid, I’m just being clever.

I beg to digress, I’m going to say more even though I don’t know what I’m saying.
