Gives New Meaning To R&D

(In maths class, I and some of my friends are talking off-topic as we find the workload much too difficult.)

Friend #1: “Can you guys roll your ‘R’s?”

Friend #2: “Nah, never tried.”

Me: “Yeah, it’s really easy.” *I say, rolling the ‘R’*

(Friend #1 then spends sometime finding out what other letters he can roll on his tongue.)

Friend #1: “Oh! I can roll my ‘D’s in my mouth, too!”
