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." 
The redhead then reaches out and touches it with her fingers, smells it, and says, "It smells like semen."
The blonde reaches out and touches it with her fingers, puts her fingers in her mouth and tastes it and says, "It sure doesn't taste like anyone in THIS building."
