The Mysterious Blob

A brunette, a redhead, and a blonde, all head home from work at the same time and get on the elevator. The brunette notices a blob on the elevator wall and says, " OOOOOhhh that looks like semen." She reaches out and touches the blob with her fingers and says, "It feels like semen."
