Get the mushroom burn mug.
When one drunk dude passes out at high noon with his cock on a girls cheek in the middle of the afternoon allowing for the sun to burn them. Once sobering up, the woman realizes that she has a mushroom burn on her cheek when looking at a reflection in a mirror.
Tom: Bro, did aunt Sally have a mushroom burn at the family gathering this evening??
Bill: She definitely did, but so did her daughter...

Tom: They got a new pool cleaner, didn't they?
Bill: Yes, yes they did.
