After training for and competing in four Olympic games and winning 28 — 28! — medals for team USA, you *might* think that the newly retired Michael Phelps has had his fill of the pool.

OMAHA, NE - JULY 01: Michael Phelps (L) of the United States celebrates with his fiance Nicole Johnson (R) and their son Boomer (C) after finishing first in the final heat for the Men's 200 Meter Individual Medley during Day Six of the 2016 U.S. Olympic Team Swimming Trials at CenturyLink Center on July 1, 2016 in Omaha, Nebraska.

You’d be entirely wrong, of course: While teammate Ryan Lochte was getting massacred over on Twitter, the pool is exactly where Phelps was spotted on his first official day off, with wife Nicole and son Boomer proudly at his side.

“There’s nothing like being back home!” he wrote of this adorable snap. “Great way to spend my first day in retirement!!”

How friggin’ cute are they? But seriously — was this guy secretly born with fins, orrrr???

Taking a break from the water, Boomer also posted (yes, Michael’s three-month-old son has his own Instagram, thank you very much) an adorable shot of naptime with Dad. “Daddy and I got to have a good nap today!” “he” wrote. “Mommy snuck in to snap a pic of us.”

Welp, you know what they say — you can get the guy out of the pool but you can’t take the pool out of the guy! Er… something like that?

Welcome home, Michael!
