The PT (age 5): We learned about volcanu's in school.
Me: Volcanu's? Really?
The PT: Yeah. Volcanu's come up from the Earf. The have Lava inside. Remember when we saw the volcanu at the museum?
Me: Oh yeah...
The PT: And there's a cap on the volcanu. You know what happens when the cap comes off?
The PT: It interrupts.
