Fake Etymologies

Interesting is better than true.

tes‧ti‧fy, v. /ˈtɛstəˌfaɪ/

From “testes” or “testicles.” Prior to the convention that witnesses in court would swear an oath on a holy book, baliffs or other such court officers would point a small dagger at the speaker’s testicles for the duration of questioning. This is, incidentally, the reason why women were not allowed to speak in court until the 1880s.
