What were the nicknames of Marv and Harry in the Home Alone movie?

Answer 1

In the first Home Alone movie (1990), they called themselves "the Wet Bandits." They would block up the sinks and flood the houses they robbed, as their signature. In the sequel, Marv decided that they would call themselves "the Sticky Bandits."

The reason for this nickname was that Marv developed a new "trick" for stealing from collection baskets/tins. Marv would wear a glove made out of flypaper or something, and as he walked by one of those Santas who dress up and collect money for the poor, he would discreetly slip his sticky hand into the collection basket, and then make off with the coins that got stuck to his hand.

Answer 2

Joe Pesci plays Harry, and Daniel Stern plays Marv.
