If there's ever something that makes you feel ancient, it's being reminded how long has passed since a TV show first aired.

The 20th anniversary of 'Buffy the Vampire Slayer' spin-off 'Angel' is upon us. To celebrate, Entertainment Weekly brought the cast back together.

In an interview clip from the reunion, star David Boreanaz reveals that he thought he was going to get fired when Joss Whedon took him aside on the set of 'Buffy'. Instead, he said as he recalled the 'terrible Irish accent' he was preoccupied with perfecting, he was told that a spin-off was in the works.

Can we also take a moment to let the fact that he is now 50 sink in?
