Launcelot is a clown and a servant to Shylock. While in Shylock's employ, he carries a letter from Jessica to Lorenzo. Shylock describes Launcelot as "kind enough, but a huge feeder, / Snail-slow in profit, and he sleeps by day / More than the wildcat" (II.v.46-48). Launcelot is lazy and a huge drain on Shylock's money, and Shylock is glad when Launcelot quits his service and becomes a servant to Bassanio, hoping he will be a similar drain on Bassanio's resources.
