The last time constipation and diarrhea met, constipation was on a hot streak, hitting 4 days in a row. However, the triple threat combination of Ex-Lax/Metamucil/coffee were the most dominant force in the league. The O/U was 3.5, but heavily juiced at -170. This one wasn't even close with 5 poops, easily hitting the over.
These two foes meet again today in a grudge match. Constipation has cooled off a bit, but has hit 2 days in a row. The combination of coffee and Metamucil isn't as strong with Ex-Lax out with the stomach flu.
Oddsmakers have the O/U at 2.5 -120. There is a lot of public money coming in on the over. The sharps are waiting to see the line hit 3, possibly 3.5 in the hope of betting the under.
