Family Matters - Season 1 Episode 17 -

Eddie's flunking algebra and has nowhere else to turn but math-whiz Urkel. Urkel agrees to help Edd-o on one condition: He gets a date with Laura. And just so he'll get what he wants, he takes Eddie's Prince concert tickets for collateral. Laura reluctantly agrees to go with Urkel on a "non-date," which goes just as one would expect. In the end, Harriette assures Laura that Urkel is well satisfied - and then the phone rings!
