Hahaha I fondly remember that commercial :) Especially at the end where Mr. Dumass goes, "What a dumbass!" :lol:
I also remember this commercial for Smart Beep, where a man and woman are about to go out on a date, and the man lets the woman in his car. The woman looks around carefully, then launches a loud fart. Then the man gets in the driver's side, points to the backseat and says, "Have you met Greg and Janice?" Janice says cheerfully, "We sure did!" Then the man says, "We've got chemistry here, you feel it?" Janice replies, "I felt it!" The man says, "All right, Janice!"
A true classic. You can see the commercial here:
