Poor David. Throughout the 70's and into the 80's, he and Maria were quite an item, but he sometimes had trouble winning her over. One day he was really going to impress her by learning Spanish, so he hit the books. He was going to invite her to Hooper's to have a soda "Te invito a tomar una soda." David dutifully wrote the phrase down, and memorized it until he knew it by heart. He found Maria outside, and was going to show off his bilingualism, but totally went blank. Meanwhile, Big Bird finds the sheet of paper David wrote the phrase on, practices it, and says it out loud in front of Maria and gets it right on the first try (he must have taken hints from Abelardo on Plaza Sesamo.) Maria is swept away by Big Bird's newly-acquired Spanish tongue, and the two go off for a soda together. Maria gets the date, Big Bird gets the girl, and David gets the shaft. Sometimes, even on Sesame Street, life stinks.
