I didn't feel like studying anymore tonight, so I took one hundreth of what I just crammed into my brain and wrote a poem. I rather like it. 

Old MacDonald had a Pharm....and on that pharm was....

Thiazides...make me want to run and hides
Nitrostat...I'd rather make out with a rat
Diltiazem...trade me spots with someone in chem
Lasix...i'd do better figuring out draft picks
Quinidine...migraines and nails on a chalkboard combined
Propranolol...making us memorize all this crap...I'm appalled
Amiodarone...I'd rather downgrade to a flip phone

Pharmacology...sucks.
