Nerdy+handshakes

So, ya might know me from before. If ya do, good, if ya don't, whateveh. OK, if ya don't, just refer ta me as some kinda annoyin' know-it-all math wiz, OK? And if ya don't know anythin' 'bout Nerdy handshakes, then see my somewhat more conservative colleague in Sigma. If ya //do// know me from before, I'm not going to make ya do any scrollin', OK?

So, ok, ok,... ok. Let's see,... ok so let's say ya have 4 nerds in a room. Yeah, just imagine that naive look on der stoopid face... Anyway, so some football quarterback bully kid rips all of der arms off and throws all o' them in his locker. 'Couple hours later, the nerds come to and uh, ya know, get outa da locker. So, uh, to celuhbrate, they shake hands wit each other once, not twice or anything like that, ok?But since dey each only have one locker, I mean, one hand, da numbuh of handshakes is gonna be smalla den da numbuh of handshakes wit people wit two hands. So, let me show you a picture of what I mean.
