Over the weekend, the annual event honoring Broadway's best seemed to have forgotten Bob's contributions to musical theater.
Back in 2007, Bob made his Broadway debut as Man in Chair in The Drowsy Chaperone, and he later played Pastor Greg in Hand to God in 2015.
John learned that Bob wasn't going to be included in the show even before the awards ceremony took place — so he took to Twitter to call them out.
"Disappointed to hear that @bobsaget will be LEFT OUT of the In Memoriam segment tonight @TheTonyawards," John wrote, adding that his late friend was "brilliant in The Drowsy Chaperone & Hand to God."
He then urged the Broadway League and the American Theatre Wing to "do the right thing" before the show took place.
"Bob loved Broadway and I know the community loved him," John concluded.
He also encouraged others to "make some noise" about the issue, but it appears that their noise fell on deaf ears.
