A Pennsylvania high school ordered more than 450 shot glasses for its prom, a move the assistant principal now says sent the wrong message.

As the Warwick High School students left last week's dance, the prom committee handed them souvenir shot glasses. The girls who attended last year's prom got a picture frame; the boys, a money clip.

Assistant Principal Scott Galen says: "Unfortunately, this year the junior class didn't have quite as much money."

Galen says the principal signed off on the purchase order, but that paperwork simply said "prom souvenir" and didn't identify the mementos as shot glasses. Galen says he's certain this will never happen again.

The school is in Lancaster County, about 65 miles east of Philadelphia.
