Step 3:
Loudly relate this non-sequitur:

"So, I’m sucking this guy’s cock, right? He leans down and asks me if I’d tickle his ass a little bit, like a Rusty-Trombone in reverse, and I say to him, I say, ‘what am I, some kind of faggot?’"
Step 4:
Smile broadly.
Step 5:
Enjoy watching people you don’t know try to pick up the pieces of their ruined evening.
