This is my time to shine, my body is full of useless, I can:
gleek intentionally (saving people a search: it’s causing the salivary glands under your tongue to shoot saliva, people often do it unintentionally when yawning)
open my jaw wide enough that it goes out of socket, and twofer I can then move it side to side and produce a loud popping noise
bend my thumb down to my wrist
cause my heart rate to spike for short periods even when at rest
I remember when I was a kid we were all trying to gleek and some of us could do it easily. I never could, so anytime as an adult I accidentally do it, I can’t help but laugh.
I can also gleek but it's nowhere near what my grade 11 English teacher could do. I don't know how it came up in class, but, in front of the class, she turned sideways and made the biggest arc I'd ever seen: maybe 6 feet long
