Gay condoms for Bert and Ernie?

Gay condoms are an essential for many couples - and one friendship in particular is at the heart of recent speculation that there may be more to it than meets the eye.

Bert and Ernie, long-time residents of Sesame Street, are a same-sex couple, some people believe.

In fact, a message left by Bert on Twitter a few months ago has been assumed by many to actually be a coded message outing himself as gay.

He said: "Ever notice how similar my hair is to Mr. T's? The only difference is mine is a little more 'mo', a little less 'hawk'."

Followers suggested that "mo" was short for homosexual and Bert was therefore coming clean about his real relationship with Ernie, who has been his room-mate for more than three decades.

However, spokeswoman for Sesame Street Ellen Lewis told that this assumption was incorrect.

The show describes Bert as "short-fused" and "uni-browed", while Ernie is more free-spirited and loves nothing more than playing with his rubber ducky.
