Did Shark Tank just jump the shark?

If it was for charity then somebody forgot to tell the viewers. If it was filmed on April Fool’s Day then somebody forgot to tell the viewers. Last night those in the Shark Tank were in on the gag of Nova (and Nine) presenters Fitzy & Wippa pitching a “Mup” (Mint + Coffee Cup) idea to the Sharks, asking for $300,000 for 5% of their company.
