Prof. Honeydew and Beaker aren’t just gay, they’re also into kinky SMDB stuff like electrified nipple clamps (an invention of the prof’s). The nice thing about their relationship is that all the physical abuse and mortal danger Beaker sweats is merely the front they present to the public; privately, the prof. pampers his assistant in every imaginable way, for hours on end, after every lab experiment. 
Scrivener Quite correct. It should also be noted that the good doctor stops any experiment if Beaker meeps the safe word. Beaker has never once done so. I suspect he is arroused by danger.
Scooter is heterosexual. Being one of the few Muppets who does not perform on stage, and having his job only because of his uncle, has given Scooter an inferiority complex. He fears approaching those women who interest him. Instead he uses his knowledge of the schedule, and his master keys to sneak into dressing rooms and steal unlaundered undergarments. He does occasionally peep at female guest performers. He has been caught several times, fortunately for Scooter, his shyness and sexual innocence have led the women to be flattered rather than angry. In some cases, they have been drawn to his purity and taken the opportunity to deflower and educate him.
Fozzy is also heterosexual and also suffers from low self esteem. Feeling that he is a failure with little to offer a woman, Fozzy doesn’t date. He has spent years visiting a small number of prostitutes. He pays them to tell him he is funny, and worthwhile, and for charmingly vanilla sex. When he stops trying for laughs, stops feeling sorry himself, and simply lives in the moment, Fozzy is actually a good lover. Several of the women have developed a fondness for him over the years. None of them, however, find him funny.
Rumor has it that he put’s his “ear trick” to great use while performing cunnilingus.
This thread hurts me so much.
I hope you’re happy. 
Nah, they’re way too old to be gay. Everybody knows that homosexuality wasn’t invented until 1979. <ducking and running>
