Aunt's Unfortunate End

Okay, pal, so you're the kinda person who needs a bear to explain a joke. First off, you posted this, so we know your sense of humor is...special. This joke plays on the saying 'slow and steady wins the race,' which is about taking your time to succeed. But your aunt, who said that, ended up dying in a fire, which is a fast and chaotic way to go. See? The humor is in the ironic contrast. It's like the universe said 'lol, nope' to her slow and steady approach.
