In a lighter vein…

Philosophy pick up lines: 
“Let’s put the ‘sin’ back in ‘sinn und bedeutung.'”
“I’d like to make like G.E. Moore and use my two hands to prove to you that the external world exists.”
“How do you feel about the use/mention distinction? Because if you mention it, I’ll use it.”
“I’d like to modus your ponens.”
“I’m a mereologist. I’d like to discuss the relation between your part and my hole.”
“I’m a *very* hard determinist.”
