The target sign is the pathognomonic thing seen on ultrasound in diagnosing intussusception. Also, air contrast enemas basically involve using a medical grade bike pump to reduce the stuck intestines… which is cool.

Lyrics

[verse]

telescoping further
than I ever thought we’d go
intermittent painful
crying episodes

[verse]

ileum and colon
currant jelly poop
intestine slowly dying
turning into goop

[chorus]

Intussusception
ultrasound target sign
air contrast enema
after treatment you’ll be fine
