This internet-only bank, whose parent company is insurance giant Prudential, has 1.1 million British customers.

The company admitted it was "very nervous" about the $4.5 million campaign yet, according to The Independent newspaper, it was a move to "represent a new set of values" to attract "younger and less traditional" new customers.

In the series of four semi-creepy ads, a menacing man named Rob materializes in the apartment of Stuart as he sleeps and showers. It is not clear if Rob is part of Stuart's imagination or is supposed to be real, but he gets into intimate situations as Stuart's eyes bug out but never stops the action.

The ads end with children chanting, "Egg and me, up in a tree, k,i,s,s,i,n,g."

The Independent quoted Tony Williams, head of marketing for Egg, as saying, "We considered having two women who could be gay and thought that was too edgy, and a man and woman would have been just normal. We think this is edgy but getting it right."

Spike Jones, creator of the offbeat film "Being John Malkovich," directed two of the ads, including the phone call (but not the shower or bed ads).
