Things got really weird on a major highway in the Houston area on Monday.
A woman undressed, climbed onto an 18-wheeler and started dancing.
Police say the whole thing started that morning when the woman got into an accident and drove off.
She later crashed her own car on the highway.
The driver of the semi says the woman got out of her car, jumped on his truck, took off her clothes and started dancing.
She refused to come down for about two hours
Firefighters used a ladder truck to help get her off the truck.
She's now in police custody.
Family members of the woman say she has mental health problems and is getting treatment.
