Explain SMBC — the wiki for Saturday Morning Breakfast Cereal

The comic features an old man with a combover who notices women snickering at his hairstyle. Rather than being embarrassed, he confidently presents a three-point argument for why his combover actually signals sexual prowess. First, baldness is correlated with high testosterone. Second, men in nursing homes are experienced at satisfying women. Third, a man brazen enough to wear a combover that bad in public is a man without shame or fear of social taboo -- "a man capable of anything, anywhere" who "screws like a goddamn mountain gorilla."

The absurd bravado works: in the next panel, the women have shifted from mockery to apparent interest, with one asking him to come back to her place, requesting only that he wear a hat. The final punchline -- "'Hat' better not be slang for condom" -- maintains the old man's shameless character and adds one more layer of crude humor. The comic plays on the trope of confidence being attractive regardless of appearance, taken to a ridiculous extreme.
