Aldrin Elementary School Principal Shane Wolfe ended the 2015-16 school year by allowing students to “slime” him.

For a Read Across America Challenge, Wolfe offered to be “slimed” by every student who read the most books from their class — but only the student body as a whole read 15,000 books.

The students read voraciously through the spring and as a result, reached their goal — surpassing 15,000 books, Aldrin teachers report.

Wolfe — who let the kids turn him into a human ice cream sundae last year — is pictured here disguised in wig and mustache, as is his trademark for the year-end assemblies.
