What Walks on 6 Legs, and 2 Wheels??

Huh??? Well, before I answer the riddle for you, lemme tell you why I'm asking in the first place.

There's a contest at work. The Bridgeport Hospital Employee Wellness Department has this contest going called Climb Like an Egyptian.

The goal? For teams of 4 people to climb as many flights of stairs as they can in 3 months. I'm on a team with 3 other therapists, and that riddle up there is our team name. And I have been getting pretty good at taking the stairs all the time, whether it's one floor or 10. GO TEAM!!!

ANYWAY...
We needed a team name, and since the contest had an Egyptian flair, Ed the OT thought we should do something with the riddle of the sphinx.

What walks on 4 legs in the morning, 2 legs in the afternoon and 3 legs at night?

The answer? A person! Crawling as a baby, walking as an adult, and with a cane as a senior.

So the natural progression went like this... What if they need a walker, then they're walking on 6 legs. Or, what if they need a rolling walker? Then it's 4 legs and 2 wheels.

So then I (being SO smart) tied the contest and us as therapists together and said, What walks on 6 legs and 2 wheels!?!

A Therapist, A Patient, and A Rolling Walker Of Course!!!
