No, it's BALONEY!!!
Malarkey?
Heh! You reminded me of something that happened when I was maybe 8 years old. There was a supermarket around the corner of our Brooklyn apartment, and my mom had sent me there to get some baloney. I took off, and returned a few minutes later. “Did you get the baloney?” she asked me. No, all they have is bologna”...
She laughed heartily, and it was then that I learned of the alternate spelling... :-)
