i put the phone on speakerphone and then put  it about 10 ft or so from the me.  i find myself  yelling "what? " and "hang on a minute"  a lot. when you want to hang up, grab the phone and either say "ok love you. bye bye." and just hang up or "XXXX, is this you? YOU SAID YOU'D SEND THE SUPPORT MONEY...."
 i gotta try the animal one - it sounds like fun...
