A quote from the [article][1].
In October 1965, to highlight the dropping of the six millionth pound of ordnance, Commander Clarence J. Stoddard of Attack Squadron 25 (VA-25), flying an A-1H, dropped a special, one-time-only object in addition to his other munitions – a toilet.
It’s a heart warming story.

In today’s armed forces culture - they’d have to have that approved. There would have to be a acquisition contest pitting American Standard versus Kohler (we all know the U.S. product will win!). Then there would be an extended period of lawsuits saying the criteria was wrong and the selection will have to occur once again.
Then, on to wind tunnel testing.
Then they’d have to take a VX-9 F/A-18 up over China Lake and do some high res imagery with yarn tufts attached to check for airflow. Then inert dummy drops filmed to make sure the separation was clean.
Then back to the design table to refine.
Sent the toilet to Pax River for advanced targeting and seeker upgrades.
Cost overruns on the toilet procurement will send up red flags in Congress. The toilet bomb drop project sits in limbo for 9 months while congress decides it’s fate. The representative from South Carolina agrees to allow the program to continue, but only if the toilet is retrofitted with a depleted uranium seat that must be manufactured in Charleston, SC. Nevada objects - wondering where the unused uranium toilet seats will eventually be stored. (Not at Yucca Mountain by God!). A late night session pounds out the details and the project is approved.
Weeks later, a labor strike in Charleston puts the project on halt. Four months later, the labor strike is resolved, production resumes.
Production models of the toilet reach the fleet. The explosive bolts do not match up to the ejector racks on the F/A-18 for some reason. Damn it man! The redesign costs 30 million dollars and delays the project 6 more months.
60 Minutes gets wind of the project overruns and does a special on it. Letters pour in to Congress. The Pentagon reevaluates the project.
In the end, the whole project is scrapped…no…flushed. Not a single Freedom Penetrator Precision Toilet is ever dropped on our enemy.
Years later, acclaimed author Chris Frishmuth writes a book on the failed product to rave reviews. Weinstein Company picks up the book and it is made into a movie. Leanardo DiCapprio plays the frustrated project manager for the FPPT. His portrayal of the dedication and raw emotions of the engineer wins him an Academy Award.
This is all true. Check the wiki.

Finally an Oscar 
You seem to have confused the Navy with the Air Force. Knowing a few AO’s (aviation ordnance), they’d prep the whole thing in the magazine when the gunner’s looking the other way (unless he’s in on the joke, which is also a distinct possibility), then they’d sneak it onto a portside pylon on a Hornet already parked close to one of the cats. Minimizes the chance of the Air Boss or CO seeing the thing before it goes off the cat.
Aviation types aren’t so good at paperwork most of the time, especially the variety who are ship’s company. And they’re almost as good with the pranks as the nukes.
I doubt they’d try that with a jet. The risk of that thing damaging the aircraft at separation is just not worth it.
