This is completely random, but you remind me of something that makes me laugh every time I use Google Maps navigation.
Last year I was messing around with my phone's text to speech settings, and I selected a male voice but cranked the pitch setting to the max. I proceeded to forget about it. For some reason when navigating, the voice is still the default pitch. Maybe about 1 in 20 turns at random though, the voice has the pitch cranked up to the max. It's rare enough that my 4 year old and I always burst out laughing when it happens.
