Grover counts tomatoes

[SesameMike]

Does anyone remember a skit in which Grover was learning subtraction, with someone who I think was a professor muppet? He used tomatoes in counting.

The professor asked Grover how many tomatoes were on the wall; Grover counted three. Then the professor took one of the tomatoes and threw it on the floor behind the wall. We heard a ridiculously loud smash and shattering sound.

Professor: "NOW what do we have?"
Grover: "I THINK a broken window."
Professor: "Uhh, besides that."

Of course, now they had two tomatoes. Then the professor threw one of the remaining tomatoes behind the wall. Again, we heard an exaggerated squash/splattering sound.

P: "NOW what do we have?"
G: (with a gasp "A MESS!"
P: "Uhh, besides that."

Again the professor threw one of the two remaining tomatoes...

G: "Oooh, your mommy gonna be mad at you."
P: "I won't tell her."

Of course, this illustrated that 2-1=1.

While I can't recall the exact season, most likely it was 1975-76.
