Forgetful

Despite his many failures in all fields of Science, Dr. Odd maintains his keen sense of irony.
His greatest triumph in botany was the splicing and resequencing the DNA of forget-me-not flowers to cause them to naturally produce a compound similar to GHB.
One whiff of the flowers would prevent two to four hours of memory from sticking to the brain.
Dr. Odd forgot to wear a filter mask during his research, so even with extensive notes, it took years to complete.
And when he finished these sinister frankenflowers, he couldn’t remember that he invented them in the first place.
