Spanky Makes a Logician's Funny

Don:
did i see your name on the list for the expert singlespeed race? how'd it go?

Adam:
that was my tax free donation to the race/cause. I won't begin racing until mid-June or so.
how come you weren't at Easterns?

Don:
'cause i was at granogue!

Adam:
isn't that a tautology?

"why didn't you win?"
"because I lost."

"why weren't you at Easterns?"
"cause I was at granogue."

Don:

here's another:

"how did your race go?"
"i considered my entry fee a donation to the cause"
