First way (Not so legit)
1. Go to tall grass.
2. Find an Abra. (Yeah, the Pokémon)
3. Hug him before it teleports. (Hard, right?)

Although you aren't sure where will you teleport, at least you teleported.

Second way:
1. Wait until night.
2. Sleep at the living room.
3. Wake up in the morning and ta-da! You teleported at your bedroom!

This is applicable if you have a concerned person in your house but still it is more legit than the first way.

(Note: I'm not competing with Egg. This is just for fun.)
