Light Umpads include: "Yeah" and "Well"
Medium Umpads include: "Yeah, Well" and "Now, the thing is"
Hefty Umpads include: "Well now, look here, the thing is"
And for the extreme padding, when you have no idea what you want to say: "Well now, look here would you, you see the thing is"
Umpads are a sure fire protection from the ineloquency of 'Ums' and are sure to protect you from criticism.
