The expression "catch fire" is intended as a joke; the CPU does not usually catch fire. Occasionally referred to as "SDI" for "Self Destruct Immediate".

Famous quotes containing the words halt, catch and/or fire:
“Someone is always at my elbow reminding me that I am the grand-daughter of slaves. It fails to register depression with me. Slavery is sixty years in the past. The operation was successful and the patient is doing well, thank you. The terrible struggle that made me an American out of a potential slave said “On the line!” The Reconstruction said “Go!” I am off to a flying start and I must not halt in the stretch to look behind and weep.”
—Zora Neale Hurston (1891–1960)
“My mother ... believed fiction gave one an unrealistic view of the world. Once she caught me reading a novel and chastised me: “Never let me catch you doing that again, remember what happened to Emma Bovary.””
—Angela Carter (1940–1992)
“The fire is the main comfort of the camp, whether in summer or winter, and is about as ample at one season as at another. It is as well for cheerfulness as for warmth and dryness.”
—Henry David Thoreau (1817–1862)
