Simply scrawl the following in a bathroom stall, write it in wet cement, tattoo it on someone's forehead while they're sleeping:
u=2∫as ds|u(0)=0
Hopefully, they will go ahead and
figure out what you're saying:
u=2∫as ds|u(0)=0
=2(1/2 as2+c)|u(0)=0
=as2+c|u(0)=0
u(0)=0=a (0)2+c
0=0+c
∴c=0
∴u=as2+0
=as2
Your victim's
self-esteem plummets as
your message becomes clear:
u=ass
QED.
