One Galactic Mess

I see that I've detected some words that were neglected By noted “lexicologist” to Suess I'm sure some how in time they'll create more words that rhyme But for now, I'll put the ones, I found to use For example, there's "Galactic" and I hate to sound "Didactic" But, have YOU tried to rhyme this word before ? So, l'll find a different Tactic less ridged more Elastic That I'm sure everyone, will just adore I've been writing till I'm Spastic like a nervous Geriatric But there's only two words, that will do I'll seek some Chiropractic And work on my Gymnastic In time I'm sure I'll feel as good as new I don't mean to sound Sarcastic But what kind of word's Bombastic It's the craziest word I ever heard Who made up Pleonastic And thought himself Scholastic I'm sure he must of been some loony bird How can I write with Lactic ? Or practic, prophylactic To make a poem filled with poise and grace If IT'S to be climatic and regarded as fantastic I've got to do what's Drastic, I rest my case
