"I Don't Like Mondays" is a song by Irish band The Boomtown Rats that was a number one single in the UK Singles Chart for four weeks during the summer of 1979, and ranks as the sixth biggest British hit of 1979. Written by Bob Geldof, it was the band's second number one single.

The opening verse is:

The silicon chip inside her head

Gets switched to overload.

And nobody's gonna go to school today,

She's going to make them stay at home.

And daddy doesn't understand her,

He always said she was as good as gold.

And he can see no reasons

'Cause there are no reasons

What reason do you need to be shown?

According to Geldof, he wrote the song after reading a telex report at Georgia State University's campus radio station, WRAS, on the shooting spree of 16-year-old Brenda Ann Spencer, who fired at children in a school playground at Grover Cleveland Elementary School in San Diego, California, US on 29 January 1979, killing two adults and injuring eight children and one police officer. Spencer showed no remorse for her crime and her full explanation for her actions was "I don't like Mondays. This livens up the day". The song was first performed less than a month later.
