Five Ways To Make A Memorable, TV-Style Entrance

1. Fall down the stairs like Whitney Port did in The Hills when she tripped while modelling an Oscar gown on live TV.
2. Show up in drag like DEA agent Denise Bryson (David Duchovny) did in Twin Peaks when he she helped Special Agent Dale Cooper (Kyle MacLachlan), a former colleague who previously knew Denise as Dennis.
3. Arrive in fancy dress as Jerry Espenson (Christian Clemenson) did in Boston Legal when he wore a Little Bo Peep costume to work, mistakenly believing it was Halloween already.
4. Dress to impress excess as Sam Weir (John Francis Daley) did when he wore a ridiculous Parisian night suit to school in an attempt to impress Cindy Sanders (Natasha Melnick) in Freaks and Geeks.
5. Gatecrash a party like Dawn Denbo (Elizabeth Keener) did in The L Word when she found out Shane McCutcheon (Katherine Moennig) slept with her lover Cindi (Alicia Leigh Willis) behind her back.

I See Dead People

Characters who have appeared prominently in TV shows, despite the fact that they're deceased (possible SPOILERS within):

Despite being found dead (wrapped in plastic) in the pilot episode of Twin Peaks, Laura Palmer (Sheryl Lee) appeared several times throughout the series, mainly during flashbacks as Special Agent Dale Cooper (Kyle MacLachlan) tried to discover who killed her. Sheryl Lee also had a recurring role as Laura's dark haired, spectacle wearing (and ill-fated) cousin Madeleine "Maddy" Ferguson.

Although Desperate Housewives began with her suicide, Mary Alice Young (Brenda Strong) has featured continuously throughout the series, providing narration from beyond the grave for almost every episode, while also occasionally appearing in person during flashbacks and dream sequences.

Even though Dexter Morgan's (Michael C. Hall) adoptive father Harry Morgan (James Remar) died several years before the start of the first series, he has appeared in almost every episode of Dexter so far, first during flashbacks and later in Dexter's imagination offering him advice... which Dexter mostly ignored.

Dude Looks Like A Lady

Dragtastic characters from film and TV:

High school student Chris Calder (Corey Haim) disguised himself as a girl in order to avoid being bullied by Kurtis "Kurt" Stark (Cameron Bancroft) and his friends in Just One of the Girls (aka Anything for Love).

Clarence Bell (Gary Anthony Williams) took on the persona of an assertive and confrontational woman named Clarice in an attempt to overcome his shyness in Boston Legal.

Captain Monica Stark (Charles Busch) tried to track down the culprit responsible for a series of mysterious deaths in Psycho Beach Party.

Cross-dressing DEA agent Dennis/Denise Bryson (David Duchovny) helped former colleague Special Agent Dale Cooper (Kyle MacLachlan) investigate drug trafficking in Twin Peaks.
