Elvis and Costello

A father and daughter were watching clips of the old Jack Benny Show.  The daughter remarked that she liked “Elvis and Costello” better.  This is a mashup of the singer Elvis Costello and the comedy duo Abbott and Costello.  Is it a malaphor?  It certainly is a mix of two items, albeit not idioms.  I declare, as Malaphor King, that it is one, and a really funny one at that.  Who’s on First?  Peace, Love, and Understanding.  A shout out to John Kooser for hearing this one and sending it in.
