I do remember the Yoshi's Story commercial, though:
Two friends are watching Yoshi's Story on their Nintnedo 64. One of the guys is teaching his friend how to snap out his toungue and eat fruit (a-la Yoshi). After a few miserable tries, the two friends are completely worn out and their toungues are hanging out of their mouths... The guy then looks at his friend and says: "I think you're getting the hang of it!" That was a funny commercial!
