Yes, Mr. Masked Blob is back. Although you get to know him in a different facet now – instead of his original swanky attire.
It’s fun when you get to link to your older strips in deference to your new readers. Means you finally have a worthy archive!!.
“…you are just being racist”
A rare occurance of using the word correctly! (Thank you, Mr Stasheff for that [slightly mangled] quote)
All Schrödinger references aside, this strip NEEDS MOAR NURSE.
This is one of those “open your mouth and let me have a look at that brain” things, isn’t it?
Holy Atomic Laundro-Bloopers Batman !! XD
The Quantum flux of duck poisition could be related to halflife. What is the halflife of a radioactive duck?
About 10 strips, give or take.
Duck is in a state of quantum superposition?
(“Quantum” is the modern “radioactive” after all)
it’s like Schrodinger’s duck…he’s on the left and right hands at the same time.
David is ambiduckstros! Us sleepy people reading the strip with our morning coffee hadn’t noticed the duck swapped hands! As long as the joke us funny I don’t care which hand the duck decided to chomp on!
it could be a teleporting radio active duck! 
Aparently, the duck values a balanced diet comprising the two major food groups. Left and right hands.
In other matters: David in a backless hospital gown. Nurse! Mindbleach, stat!
Don’t want to be a poop or anything, but which hand is the radioactive duck supposed to be attached to?
;o)
It’s SUPPOSED to be the left. But now I’ve noticed I kept changing hands. I actually noticed that mistake as well two strips ago – but flipping the drawing just didn’t look right to me.
