Not long odds, not for a fairly can't-miss cultural reference joke like that. Let's say each joke would have won it's resepective race as a fairly heavy favourite over the other, more hit-or-miss jokes. So let's take an example from today's results. Today's last 3 races at Fairmount Park were won with each of the winning horses not paying that much on a win ticket:
#2 Flying Cayman won the 6th and paid 3.40 to win
#1 Runaround Jonnie won the 7th and paid 6.40 to win
#2 Wildwood Pegasus won the 8th and paid 3.80 to win
(All based on a $2 ticket, of course.)
The winning 2-1-2 $1 Pick 3 paid $8.90.
Of course, that number varies not just by the odds of each winning horse, but by how much was bet on the Pick 3. Not being privy to their formulas, but knowing that the pool was $1057, which seems pretty standard for them (Fairmount Park isn't a very big or popular track, so the pools tend to be smaller), I reckon that the payoff of $8.90 is about right for the payoffs of the 3 winning horses. Or in other words the odds are fairly standard and not too skewed by an inflated pool on the Pick 3.
