Med students and doctors, let's laugh at ourselves. What's your most purulent stuff you've ever moved in clinic or rounds?

Okay, since nobody is doing, let me start.
I once clerked with a colleague and we wrote +ve hx of seizures and convulsion
Conso: What's the difference?
Me with confidence: Convulsion is the one that has foam, seizure doesn't have foam.

PS, the consultant is on twitter.
