 As the last line, "Here's a toast to dear old Penn," is sung, the fans send toast hurling through the air onto the sidelines.In another version of the origins of toast throwing, in 1977, a student threw the first slice of toast after being inspired while attending a showing of The Rocky Horror Picture Show where members of the audience throw toast at the screen.In more recent years, some students have become more creative in their choice of projectiles, and it is not rare to see a hail of bagels or donuts, or even a loaf of French bread come flying down from the stands.
