The Show-Off (1946)

Aubrey Piper (Red Skelton) is a big-talking blowhard with huge ambitions and very little smarts. After lying and bragging about his past, he's eventually able to convince the gorgeous Amy Fisher (Marilyn Maxwell) to marry him. However, he has difficulty earning the favor of Amy's mother (Marjorie Main), father (George Cleveland) and sister (Jacqueline White) after he nearly burns their house to the ground and puts them on the brink of financial ruin.
