James Tate, a student at Shelton High School, told Hearst Newspapers he taped the letters in a "safe and thoughtful way" late Friday and even wore a helmet while he climbed a ladder. But school officials apparently decided sneaking on campus in the middle of the night was out-of-bounds behavior.
Tate's message read: "Sonali Rodrigues, Will you go to prom with me? HMU Tate."
Tate and his two assistants were given one-day suspensions. Shelton High rules are that anyone suspended after April 1 is banned from the prom.
"I tried to appeal -- tried to just get a detention instead," he said. "I even offered to do community service -- like cleaning up the litter outside the school. Now I have a date for the prom, but can't go."
Rodrigues still plans to go to the prom. Her date is another girl whose boyfriend was also suspended for another incident.
