Cartoon Network has featured its first ever openly gay characters in the comedy series ‘Clarence.’

In the episode “Neighborhood Grill” which aired on Thursday, the two male characters are depicted kissing each other on the cheek as they greet one another in a restaurant scene.

However, the show’s writer Spencer Rothbell told the Huffington Post the kiss was originally intended to be on the lips, and one of them gave his partner flowers.

The scene had to be changed in order to be green-lit by Cartoon Network.

He said: “It’s such a minor throwaway moment but I guess it’s better than nothing. Maybe one day the main character can be gay and it won’t be a big deal.”

Earlier this year the Disney Channel featured its first ever gay couple, in sitcom ‘Good Luck Charlie’.

However, a 5-year-old actress on the show began to receive death threats on her Instagram account shortly after the episode’s airing.
