To be done while one is getting a blowjob:

Just before you climax, say something funny. If done correctly and timed perfectly, the girl will laugh as you ejaculate. Because she is laughing, the semen will squirt out her nose.
"Tina really found that joke funny, and I should know. When I said it, I turned a regular blowjob in a Chuckling Blowjob."
