John Stamos is currently appearing as himself in a commercial for Propel water product, not as a spokesman but in the midst of a paparazzi swarm.
As it was a fictional scenario, then the blipvert can be linked to the following shows in which he played himself:
"The Larry Sanders Show"
- The Prank (1997)
- 0.409 (1995)
- Surf's Up (1995) (as a member of the Beach Boys)
"Step by Step"
- Great Expectations (1994)
Turns out that I really should watch commercials right to the very end. (I also should do something about this ADD....) Apparently, the woman is fantasizing everything she sees during her power-walk, including Stamos (and Derek Jeter).
Still, she knew who he was, and in the Toobworld sense that gives him validity as his own tele-version. So while not a full-out link to the other shows, it can add flavor to Stamos' standings.....
something like that.....
