Students at Lakewood High School in St Petersburg spotted the basic grammatical error on the giant sign and immediately began posting pictures of the message online.
The mistake happened when hapless teacher Austin Simmons arranged the sign to promote the school’s leap day literacy event.
Unfortunately the sign read: ‘LAEPING TO LITERACY NIGHT’.
Mr Simmons had other things on his mind last Friday after receiving a large motorcycle repair bill and failed to double check his error.
Literacy coach Patricia Schley, who is hosting the night, spotted the sign as she drove past the school but had to wait until the school opened on Monday before she could change it.
Horrified principal Robert Vicari defended his fellow staff member, reassuring parents it was just an accident.
‘He’s a great guy. And he’s literate. This was just an accident,’ he told the Tampa Bay Times.
‘It’s every principal’s fear. I sure hope that sign doesn’t end up on Jay Leno.’
