This tweet tells me a couple of things about Huckabee. One, he's afraid of the word "toilet." Two, he thinks that when you flush a toilet, the water jettisons out of it, resulting in a horrifying crap fountain that dapples the walls with flecks of poo.
The autopsy of this tweet requires a bit of legwork. It was posted on February 28, the day Trump made a speech to Congress. I believe the joke is that they left too quickly after the speech, because they were eager to reap fabulous savings at J.C. Penney's. This is nonsense, as democrats clearly shop at Nordstrom's, the lib-cuck's retail paradise. To see if I'd understood the joke correctly, I ran my hypothesis through my Huckabee Analysis Machine, the Huckatweet 9000, and had it translate from Estonian to English.
If you squint and shoot up with black tar heroin cut with crushed glass, you might be able to see a joke in there.
