This reminded me of an instruction on the Power PC Micro Processor:
Enforce In-Order Execution of I/O with the assembler code of EIEIO
I considered this to be the Old McDonald of instructions.

Hey, when I was in my 20's and programing the 6809 that was fun.
In the UK
there was a home computer based on the same Motorola
schematic called the Dragon. Similar to the CoCo, but not identical.
Anyway it was well-known at the time 'You can have SEX with a Dragon'
