Goes to show the subjectivity of humor. I LMAO at this, but two guys I shared it with found it not one bit funny. Sigh....
This reminds me of a tweet I once read that went along the lines of:
---
<surgery is about to begin>
Surgeon: Alright, let's get started.
Female patient:
re-arrange my guts, daddy! (written in highly cursive font)
Surgeon: Is this woman sedated?
Surgical team: We've given her so much sedation...

I forwarded it to my friends, none of whom are strangers to sexual / downright crass humour, and one of them was responding as if they totally didn't get it.
