Why did the musician get locked out of their own gig? Because they had too many bars and couldn’t find the right key!
I tried writing songs about the electrical grid, but I couldn’t generate any current hits. Guess I'm just not well-grounded in the genre.
Ever heard about the Motown band that also worked in IT? They were called The Temptations to Hit 'Refresh'. Their top track? "My CTRL".
