This being the Internet, I have been carefully observing you for evidence that youre really a doctor. (See also, Im a sexy girl.) Cogent scientific discussion in a professional tone with reference to the literaturewell, I found that unconvincing. It could be faked. But now that I see your penmanship, I will vouch on your trust page that you are genuinely a doctor!
(Now, I must apply my skills at forensic handwriting analysis to revenge for your having doxed my name and photo...)
I'll have you know that I Googled* "Joke over head" and used the first image I found. I'm not so careless as to expose my handwriting to the internet!
As a side note, your anchor tags alone make better reading than half the posts in this thread.
*Not actually Google, but one of several privacy respecting search engines that exist. If you want to find a similar engine, trying Googling it, heh.
