I have come up with a lame poem based on various expressions my husband uses (and some he doesn't use). My children think it is funny and recite it when he uses the expressions.
Ug, ug, my name is Doug.
When folks say hi, I just shrug.
Ack, Ack my name is Jack.
When folks say hi, I smile back.
Oh no, my name is Joe.
When folks say hi, I say Hello.
