Name games
I'm developing the same disease my grandmother has. For my whole life and well longer, as far as I know, she does the same thing when she gets flustered and needs to summon either my aunt or my mother -- "Marcia-Sandy!" "San-Marcia!"
Now it's my turn. Bob's become "Ja-Bob" and James has become "Bo-James."
The disease is communicable too. Bonnie caught herself calling James "Em-James" the other day.
