Somebody who no matter how hard they try and keep a straight face while looking in the mirror, are secretly laughing at the funny lookin guy/girl looking back at him/her from the inside of the mirror.
Funny lookin guy/girl looking in the mirror- Today, you're gonna keep a straight face for five minutes. Don't underestimate yourself, what is that a smirk forming in the corners of your mouth? You want to keep your teeth? Yea, keep a straight face on your face. If anybody messes with you, say what you just said, just like you just said it. What was the other thing Kevin's big brother said when he was 5? Oh yea, what are you lookin at? That's what it was. Say that too if anybody looks at you. You just gotta keep practicing, 5 minutes, 6 minutes, 7 minutes.

The idiot who hears your joke, which was such a good one, and he tee-hee’s and decides
To say “gee, funnie-wunnie!” What most don’t know is by saying this it literally kills
About 89.72% of your brain cells. So take heed in front of idiots.
