Watch: Shaq's mom rolls onto court in mini 18-wheeler

More than 16 years after Shaquille O'Neal rolled down Biscayne Boulevard in an 18-wheeler to announce his Miami arrival and promise a championship to the city, his No. 32 was retired in a halftime ceremony at American Airlines Arena.

Naturally, Shaq's mom, Lucille O'Neal, was there to celebrate her son's big night. In throwback Thursday fashion, she proudly rolled onto the hardwood in a mini 18-wheeler.

Outstanding.
